Episode 1.

They say if you touch a mermaid without caution, the mermaid will take the human's soul and erase their memory. That is the way the mermaids defend themselves against humans.

I'm not sure about the academics, but I never lost first place for visuals. – Kim Dam Ryung

The worlds that a human and mermaid live in are clearly different, whether it's good or bad destiny, what use is it to form ties with it? – Yang Seung Gil

A long time ago, mermaids lived in any part of the ocean. But now, most of them have disappeared. They say that the last mermaids that remain on this Earth live in this ocean.

They say those bound to succeed en up throwing overhead kicks even when they fall backwards.

Are you from the jungle? Are you a werewolf maiden? Why are you so instinctive? – Heo Joon Jae

Wait is a word that means something good is going to happen. A word that even when, like a wave, I go somewhere far away for a bit, my friend will find me. A word that even when there's something scary like a shark around, you don't have to be scared or look around. A word that means my friend is wishing for me not to get hurt. A word that warms the heart.

Episode 2.

It was a fated bond that should not have been made. But since it is already made, that fated bond will definitely continue. They will meet again.

Do you know what I hate the most? Leaving without saying goodbye. That's why I came, to say goodbye before leaving. – Heo Joon Jae

Love is actually something quite dangerous. – Heo Joon Jae

If you love someone, it means you surrender. – Heo Joon Jae

If I wasn't weird and had a name, I could be with you all the time, right? – Sim Chung

My hand, you could've left me but you held it, several times. You're a good person. – Sim Chung

This is the end of the world? There is the ocean, why is it the end? – Sim Chung

There is a legend. People who separated from here will surely meet again. It's probably even though this is the end of the world, this is also where another world begins. – Mo Yoo Ran

Episode 3.

Se Hwa, it means a bright, shining child.

I don't want to leave you. I don't want to protect and like another girl. I don't want to live with her f forever, if it's not you. – Kim Dam Ryung

Mermaids have a special ability. It is that by kissing a human, they can erase memories of themselves from the person. Just like that, the mermaid disappeared like sea foam from the child's memories.

You probably won't remember me. Still, I will keep my promise. I'll go to you. Even through the windy rainstorm, though the sun may be burning down on me, though I'm lonely and without anyone by my side, and even if it's somewhere I've never been before, I will endure it all and be sure to go to you. Saranghae. – Sim Chung

Episode 4.

The mermaid who has fallen for a human always comes to land. That is part of their inherent nature. For a mermaid that can only love once their lifetime, she stakes her life on that one love.

Protecting others comes after protecting yourself. The order is like that. It's a stupid thing to switch the order. – Heo Joon Jae

Usually, good and pretty things disappear quickly. Like this, you look at it well and then keep it in your heart. Then when you have a sad day, you think about it. – Mo Yoo Ran

I like that I'm with you. – Sim Chung

Episode 5.

Flowers in this world have their own special meanings behind. This means something you have but I don't... it's memories. – Kim Dam Ryung

I had a dream. Inside that dream, I am living in a strange world. You were also there. I painted you and me from what I saw in my dream. If that's just a dream or hallucination, or if I'm seeing the future of another world, I can't know exactly. One thing is certain, that the things happening now will also happen at that time... just like that, strangely. The fact that this fate is repeating again. – Kim Dam Ryung

I'm good at waiting. – Sim Chung

Episode 6.

You kept your promise but I still haven't fulfilled mine. – Heo Joon Jae

I will keep her in my heart, no matter how much it hurts, until I die. – Ae Yeon's Mom

Do people want to remember even the pain and sadness? What kind of love would it be to want to remember it despite being so painful that makes you unable to eat or sleep? – Sim Chung

Episode 7.

In my dream, we were born again. We met again and were together. You came from a faraway ocean to meet me. And though I could not remember you, you were already in my heart. – Kim Dam Ryung

In the future, I won't let you go if you bother my friend. – Sim Chung

The moment that a mermaid leaves the water for land, her heart starts to harden. Even if your legs don't, your heart has a time limit. There is only one way you can continue to breathe and keep your heart beating on land. It is only possible when the person you love loves you back. That is the only way your heart can keep beating passionately. – Yoo Jung Hoon

Jealousy is the fastest path to love. – Yoo Jung Hoon

Why do you think mermaids are in the brink of extinction? It's because we don't change. Humans change but we don't change like idiots. That's why we get stabbed in the back. – Yoo Jung Hoon

Humans change. The woman I loved did, too, even though she said she'd love me forever. – Yoo Jung Hoon

There doesn't exist any human on earth who can accept us the way we are. – Yoo Jung Hoon

Episode 8.

What little consolation that a thing called lie exists here. – Yoo Jung Hoon

My heart has reached its limit. – Yoo Jung Hoon

It is too harsh to have a heart that's reserved for only one person. – Yoo Jung Hoon

Joon Jae: The easiest thing in the world is to be disappointed by another person. There is no one who overcomes disappointment. So, loving another person is the most difficult thing.

Sim Chung: For me, loving someone is the easiest thing to do. Even when I tried so hard not to, I couldn't help but to love. No matter how much I wanted to be disappointed, I couldn't. For me, love overcomes everything.

Secrets are made because people are different, because you would have to not get caught being different. – Kim Hye Jin

He hoped those memories would stay with the person that he loves and give that person strength. – Sim Chung

Sim Chung: I will go back to the place where I was, before it's too late.

Joon Jae: You told me to tell you if I have plans of liking you, right? I have a plan. So don't go.

Se Hwa: If I didn't erase your memories, I knew you would be in pain all the time.

Dam Ryung: If you didn't erase them, then I could have longed for you all the time. This time, do not erase them. This memory, this remembrance, even if it hurts, it's something that I will bring to the end. It belongs to me.

Everything is repeating itself. That fate that happened here is also being fulfilled there. Ill-fate is like that as well. – Kim Dam Ryung

Life is all about something that is about to work out but then it may not. – Heo Joon Jae

There are three steps of love. The first is romantic love, the second is hot love, and the third is dirty love. – Beggar

You gave up... on mom and me. And the time that we were together, you threw it all away... without looking back. – Heo Joon Jae

Since you gave up and chose something else, don't hold on to what you let go and just forget it. – Heo Joon Jae

No matter what you say, I'll stay by yourself without giving up. – Sim Chung

Thinking about it, she really doesn't take responsibility for her words. – Heo Joon Jae

So this is how lying feels like. It makes my heart pound a little, but it is convenient. – Sim Chung

Even if you are different, no matter how different you are, I won't leave you. – Heo Joon Jae

If you know who I am, you will be shocked. You will be hurt and scared. You will leave me. That's why I am trying my very best not to get caught. – Sim Chung

Even if you erase his memories over and over, even if he's born in a different world, he is a boy whose fate is to love the mermaid again. So in the end, he is the boy who will eventually hear the mermaid's voice again. He was me. – Heo Joon Jae

Why am I not disappointed in you when you're a bad guy? Why can't I leave you, who fooled me? – Sim Chung

There are many things that he failed to protect and ended up losing. – Heo Joon Jae

When I crossed the long ocean to find you, I saw these stars every night. But I was lonely because I was alone. I was tired. I was scared. But right now, is it okay to be this comfortable? Is it okay to be happy? Is it okay to love you? – Sim Chung

I promise, if we are born again, I will find you, meet you and protect you. – Kim Dam Ryung

Episode 14.

For someone to be reborn, wouldn't that mean there's a dream that hasn't been fulfilled yet? That dream could be an unfulfilled love or an unappeased greed. – Jin Gyung Won

If you didn't love her, and if she didn't love you, then there wouldn't have been such a tragic ending. Your love for each other ended up killing both of you. – Jin Gyung Won

The fact that everything has repeated is not a curse but an opportunity, an opportunity to change the ending. – Heo Joon Jae

There must be a reason to remember everything. This time, I will protect her. – Heo Joon Jae

If you live, I have to live with you. And if you die, I have to die with you. – Sim Chung

You can't change fate easily. – Jin Gyung Won

My heart can only beat if you love me. – Sim Chung

What the legend of the lighthouse stated is true, that those who get separated there will surely meet again. – Sim Chung

Episode 16.

Among the many words I've come to learn after coming here, the best words are happy ending. I'm sure that this very moment is a happy ending. But the hope and despair that life gives you is that time keeps flowing and the moment passes. Behind that moment of brilliant happiness, no one know what kind of moment awaits. – Sim Chung

Despite knowing all of it, I just couldn't regret it. Meeting you was something I could not regret no matter how I saw it. – Heo Joon Jae

You should know this by now, that even if I'm not by your side, the fact that I will continue to love you. – Heo Joon Jae

Joon Jae, your father was wrong. You were right. My decision was wrong from the start to the end. I'm not sure why admitting that was so difficult. I'm not sure why it took so long. I always missed the times together with you and your mother. I wanted to return to those times. Why did I live without accepting that feeling? Why were the words I'm sorry so difficult to say? I'm so regretful now. If I were to be born again, I'd like to live once again as my wife's husband and my son's father. I suppose it's just my greed? I'm sorry, Joon Jae. I love you, my son. – Heo Il Joong

From now on, I'll keep making you smile. – Sim Chung

You know my principles, right? First, money. Second, even more money. Sadly, the third doesn't fit: manners. – Jo Nam Doo

Episode 19.

The ending has changed. This time, I saved you. – Sim Chung

Having you as my mother is a curse for me. – Heo Chi Hyun

I may be a guy whose eyes become blinded by money, but I keep true to two principles. I, without fail, pay back my enemies. I pay back my debts if possible. – Jo Nam Doo

I thought about it and realized life is short. I feel that my love will be longer than my life. That's why in this life, my love won't end. – Heo Joon Jae

At times, couldn't the fear be better than the reality? – Jin Gyung Won

Because of a sin that I can't even remember, I can't live paying the punishment. – Ma Dae Young

You never know what's going to happen to your life. Don't just look at your present situation. Even if people don't change, circumstances do. – Ahn Jin Joo

Was this what you wanted? To be erased from the world completely so that even I would forget you? – Heo Joon Jae

In this world, only I remember you. – Heo Joon Jae

Erase my memories 100 times and see if I forget you. – Heo Joon Jae

You could not erase yourself from me. You are remembered by my body and engraved in my heart. – Heo Joon Jae

Finally, we made our dream come true. In a village where not much exists, not much news occurs, in a small boring village with nothing special, having a very very simple life, while crying and laughing at very simple things, being happy and being sad, while quietly watching how our time together flow, each day, each hour, each minute, each second, after taking many detours, treasuring the love that finally came to me, as we remember our legend that's far off, beautiful and secretive.
