(I suggest you play the song when you read "I started playing")

~Frisk POV~

It was already night. Wow, time goes by so fast. I lie down on a queen sized bed. My room is color pink and blue, a mirror stood in front of the bed, 8 feet away. A white closet beside the bed, it was full of fancy gown and dresses made by, who was that? Oh right, it was made by Mettaton the robot. I wore a white night gown with long sleeves. I sat up and frowned. I'm not yet sleepy. I stood up and searched for a simple dress. I saw a dark blue long sleeved dress until my knees with a v-neck. It has a star on the right side of my chest. It also has two thin sky blue stripes at the end of the dress. I brushed my hair and wore matching dark blue shoes. I left my room with the door open, the moonlight through the mirror went out my room. I felt someone was watching me. I turned but saw no one. I searched every room in the 3rd floor. It was nothing really, the rooms were mostly full of paintings and statues. I went down the 2nd floor. I passed three doors and stopped at the purple one. All the other doors were mostly red or blue, but this one has a different color. My curiosity got the best of me and I went inside. I only saw musical instruments like a harp, drums, guitar and more. I saw a ukulele and walked close to it. I grabbed it and went to find a chair. When I did, I sat and tried to remember the how to play a ukulele. Dad taught me when I was younger. I thought of the lyrics and I started playing. I closed my eyes,

'If your evil and your on the rise, you can count on'
'All of us taking you down. Cause we're good and evil never'
                                                    'Beats us, we can win the fight and go out for pizzas! We will get'
                                                   'Out of here and see the light of day. And if you think we can't,'
                                                     'We'll always find a way. That's why the people of this world believe'
                                                     'In, all the monsters here and Frisk the human'

                                                        'If you could only know everything we are, when you'
                                                       'Came here to us from beyond the barrier. We were amazed'
                                                         'To find your beauty and your worth. And we will'
                                                        'Protect your kind, and we will protect your earth, and'
                                                        'We will protect your earth and we will protect you.'

                                                        'We will fight for the place where we're free, to live together'
                                                          'And exist as we. I will fight in the name of Asgore and'
                                                         'Everything that he believes in. I will fight for the world I was'
                                                           'Made in, the earth is everything I've ever known. I will'
                                                          'Fight to be everything, that everybody wants me to be'
                                                         'When I'm grown. The odds are against us, this won't be'
'Easy but were not going to do it alone. We will Get'
'Out of here and see the light of day. And if you think'
'We can't, we'll always find a way. That's why the people'
'Of this world believe in, every monster here and Frisk'
'The human'

I stopped singing. "You have a voice like an angel" I very familiar voice said. I opened my eyes and turned, I was surprised to see Sans leaning on the wall, both hands in his pockets. "I-I'm sorry, did I disturbed your sleep?" I asked, holding the ukulele to my chest. He chuckled. What's so funny? "No, it didn't. I was already awake when you left your room" he said as he walked closer to me. When he was close enough, he cupped his hand to my cheek. "Tell me princess, why'd ya' made that song" I looked up at him. "Sans, I already know." He gasped then smirked at me. "You sneaky little princess~" he said as he pulled my face closer to his. I can feel his warmth. I blushed intensely. "Don't worry Sans, your kingdom will get out of here too" I said. He pulled me closer and he kissed me, my lips touching his teeth. I blushed, and I melted with the kiss. I closed my eyes, the moonlight through the window shining down at us.
