New characters and (not so fluent) japanese words ahead!

A knock can be heard from the other side of the door, gaining Youngjo's and the others attentions as he approached it closer before opening the door.

Discovering two friends of his, greeting him with a warm and gentle smile. One of them push his glasses up to the bridge of his nose and open his mouth.

"It's great to see you again"reaching out his hand to shake."Likewise, Doctor Seungjoon"

"No need to be formal. Just call me by my name like you used to"Seungjoon smiled again and introduce the other guy beside him.

A Japanese guy who is an IT expert named Mizuguchi Yuto as Youngjo shook hands with him.

Dongju, Eric, Chanhee, Sunwoo and Jacob are watching them from afar. They exchange glances with each other, questions on their faces.

"I'm glad you called me. So who is this vampire you talked about? I'd like to meet him"Seungjoon asked, taking a glance on each unfamiliar faces in the room except for Jacob because they know each other for a long time too.

"Chanhee come here"

"M-Me?"

Chanhee didn't expect them to be talking about him. He point his finger to himself somewhat feeling nervous about it as he saw Youngjo nod his head.

He stand up from his seat, releasing Sunwoo's hand in his grasp and take a few steps towards them.

"Chanhee huh? What a pretty name"Seungjoon let out a soft chuckle, teasing the pink haired boy.

Sunwoo was already glaring at the guy, curling his hands into a fist. Dongju saw the face he was making, smirking to himself.

Knowing the look that says 'Don't touch nor flirt with my boyfriend or you're dead'

Chanhee couldn't help it but to blush at Seungjoon's compliment and tried to act like it didn't affect him.

"You don't have to worry so much. I'm not gonna steal him away from you"Seungjoon points it out and chuckle once again, making both Sunwoo and Chanhee to blush harder.

"Mattaku (Oh geez)"Yuto sighed, shaking his head left to right."We're here to discuss about his bloodlust"

"My bloodlust?"Chanhee furrowed his eyebrows."What about it?"

"We heard that you can't really control your bloodlust whenever you see blood so we're here to help you how"

Everyone showed interest about it as Chanhee looked at Sunwoo for a second before turning back to Seungjoon, accepting the offer.

Settling down first by sitting down on the vacant seats, Seungjoon begin to explain about bloodlust and why Chanhee feels the need to drink humans blood.

It was due to a beast. A beast that placed within inside of him where it awakens his hunger or thirst for blood. But there's another reason why he felt the bloodlust or felt like vamping out.

That's because he imagined himself leaping on people, ripping their skins off, slashing their necks as they bathed in blood.

The beast kept on giving him violent and gory scene, trying to persuade him to do that kind of thing.

"So you mean this beast is the one trying to take control of my body?"Chanhee asked a question, pointing his finger to his abdomen.

Seungjoon nod as a respond and adjust his glasses."But how can he control his beast to prevent it from their outrage?"

A curious Eric asked, eyes in anticipation as he waits for the answer to be given.

"The solution is simple. Just have sex with the one you like!"Seungjoon chirped cheerfully, surprising them with his answer especially Sunwoo and Chanhee.

They were in a blushing mess. Hearts already thump so hard against their chests and Sunwoo couldn't stop to overthink about doing it with him plus he told himself he's not completely ready at that level.

What if I messed it up? What if we forgot to use protection? What if it hurts? What if I get pregnant? Wait does men can even get pregnant? I must be out of my mind!

Sunwoo was lost his thought on his what ifs questions that lingers in his mind. He can feel his temperature rising to the top as if he's gonna combust at any moment.

"Yamete kudasai Senpai (stop it)"Yuto once again sigh, facepalming."Omoshiroku nai yo (it's not funny)"

A laugh can be heard from Seungjoon's mouth, making them to look at him in confusion.

"You're still the same like in the old days"Jacob spoke up, shaking his head left to right.

"Same goes to you Bae"Seungjoon smirk when he saw Jacob rolled his eyes."I told you not to call me that. Only Sang-- I mean... Just don't okay?"

"Alright sorry. I'm kidding"

Eric saw the face Jacob was making. Jacob casted his eyes down with a sorrow expression plastered on his face. Obviously it reminds him of his dead husband.

Youngjo squint his eyes at him. His brows already knit together as he tilted his head a bit. Questioning himself about what Jacob had said.

Seungjoon seems to know something that I don't, he said in his head.

"Wait what?"Chanhee put on a face and scrunched up his nose."So you were just joking about the sex part right?"

"Yeah sorry about that. Can't help teasing you guys. You two are just too adorable being so easily flustered"

Seungjoon fake a cough and get serious."Okay moving on~"

"Wait! I have a question!"

It was Eric again. He actually has a lot of questions to ask but he's curious about a certain vampire who's controlling the beast without a problem.

"You see, Dongju is a vampire but I haven't seen him so out of control when he sees blood"he pointed his finger towards Dongju who's sitting next to him."Is it because he kept this tiny jar of blood or is he good at controlling them?"

"Now that you mentioned it..."Youngjo trailed off his words while holding his chin, thinking.

Seungjoon form a smile, faint blush crept up through his cheeks as he thought of someone.

"You're quite a unique one. That reminds me of my lover"he giggled and Yuto rolled his eyes in annoyance.

"To tell you the truth, I don't really know. Sometimes it depends on the situation. But the most accurate answer is the jar of blood he kept for himself"he told.

"That's because whenever he felt thirsty for blood, he'll just drink the blood from the jar. Even just a drop will quench his thirst and that's also why he never out of control"

Each one of them nod their heads in understanding of what he explained but Eric seems to not get on some part.

"To summarize it all, Dongju has a weak beast"

Finally Eric understood as he formed his mouth an O shape. Then does that mean Chanhee has a strong beast, you might ask.

You are correct but the beast inside is a bit different than the usual.

It's the stubborn type of beast and that's why Chanhee easily changed into a monster.

Just like Naruto who couldn't control his jinchuriki that sealed inside his body when he was a kid.

"So in other words, you also meant that Chanhee is weak right?"Sunwoo sound so offended by it, clenching his fist.

"No no! I didn't mean it that way. He's a strong guy. He just need some time to master on how to control the beast"Seungjoon raised his hands up, placing it in front of his chest and shake them.

"Enough about the beast. Let's get into the important part"Seungjoon clap once, to see if they are still focus on what's he gonna explain next.

"Yuto, the items please"

He ordered Yuto to take out something from his backpack as he placed it down on the table.

All eyes were glued on the strange items. Sunwoo scan each every of the items, finding it kinda odd.

Is this pointy thing some kind of an armor or something? He questioned in his thought. Chains? Collar? And handcuffs?

"I don't get it. What are these for exactly?"Chanhee tilt his head,

"Anata wa hontouni bakada yo ne? (You're really an idiot huh?)"Yuto answered it before Seungjoon could open his mouth.

"More specifically, you'll be using these while doing it with your boyfriend"

"W-What?!"

Dongju grab the handcuffs from the table and raise it up."Wow. Kinky"

Both Sunwoo and Chanhee blushed again. Their eyes met with each other for a brief moment but one of them decided to tear his gaze away, breaking the eye contact.

"Oops~ My bad. I still haven't explain on how to control your bloodlust while using these"

They sat down on the edge of the bed in unison as it made a soft creak sound. Facing their bodies towards the device in front of them.

A laptop placed on the stool, showing a face of the doctor and his IT expert who set this up and connect it with his own laptop as they were doing a video call.

Yuto did program something in the laptop, clicking this and that which they don't understand at all. I mean only IT expert knows what they are doing and get what it means.

They actually in the other room which is right next to Chanhee's room. Seungjoon begin to speak.

"If I tell you to stop, be sure to stop okay? I don't want things to get out of control"he smiled, and saw them bounce their heads up and down."You two can take your time. No need to rush alright?"

Before the two adults could respond to what he said, he ended the video call as the screen shows some numbers and a meter that sensors Chanhee's temperature.

Yuto explained it to them beforehand that if Chanhee's temperature heat up, the meter will rises from time to time. There's also a straight line that labeled WARNING in between the red zone and yellow zone.

If his temperature reaches the red zone, it'll be dangerous for both Chanhee and Sunwoo which means Chanhee might gets out control.

So to prevent this from happening, they already planned it by putting those finger armors first in each every of Chanhee's fingers. This is to protect Sunwoo from getting clawed from him.

Awkwardly sitting across from each other, they were holding a staring competition for a few seconds until Sunwoo spoke up, somewhat nervous.

"Are you ready?"
