Hyungwon is that typical type of guy that makes girls go crazy. He came from a wealthy family with a handsome look, slim and tall body and this amazing looking pump lips. He's always acting cold and keeps his distance with everyone. He has this mysterious aura and his grades are always high. As a lady-killer guy himself he always receives love letters from the girls and he had a large number of girls telling him to be their boyfriend too. However despite everyone's expectations he doesn't have a girlfriend or anything like that. In fact he practically ignores all of the love that girls gave him. But every time a girl asks to be his girlfriend they will always receive the same answer : " I'm already taken so stop trying and leave me alone." 
He has friends though, even closed friend - Changkyun who went to the same secondary school as him and skipped class to jump right to high school due to his intelligence at the age of 14. Changkyun is the only person he talks to.
It was a normal day at the highschool and Chae Hyungwon got himself another request from a girl. "Meet me at the back of the school yard " she said. And so after school finished he went there with his regular cold expression or even almost like a " I have went to s so you better don't piss me off " face . 
There he was standing under the tree, listening to a pretty girl saying 
"I like you a lot and I've liked you since the day we first met so do you want to be my boyfriend ?"
The girl asked and her cheeks turned lightly red due to shyness. If anyone got a request like that from such a pretty girl they would the more than happy to be her boyfriend. But this is Chae Hyungwon we're talking about and frankly he didn't care about anything but his study and dancing .
" you girls are really stubborn, aren't you ? I've told you many times I'm taken and I don't have any intentions of cheating on my lover so my answer is no. Are we done I have things to do ."
His answer shocked the girl for a moment because she has never been refused before and that made her piss.
"Why don't you accept me. I'm pretty, smart and all the other guys want me. What is so good about your girlfriend that even though she's not here that you still choose to be loyal to her ? What does she got that is better than me"
The girl started screaming and didn't take his no for an answer. All of a sudden a voice spoke up in the back of the tree
" well young lady "the girl" you were saying has one thing you'll never have that is Chae Hyungwon's love . Besides I'm much more beautiful than you so face it"
The voice shocked both Hyungwon and the girl. Hyungwon immediately turned around and was excited when he saw who was standing there. He smiled and opened his arm. The person ran towards him and wrapped their hands around Hyungwon's waist, pressing their face into his chest so they could sense Hyungwon's smell around him. Hyungwon tighten his embrace and nuzzled his nose in the person crook.
"Babe, I miss you so much. Living a day without you just feels like dying. Hoseok, my baby don't ever leave me for that long again ok"
His words got Hoseok chuckled and rubbed his cheeks against Hyungwon's chest .
"I missed you to babe"
Hyungwon lifted Hoseok's face up by his finger and gave the boy a deep kiss that got Hoseok gasping for air when they are separated. He lifted Hoseok up and spin him around which made the blond boy chuckled even more. He dropped Hoseok down but hands were still on the blond's waist. He turned to the still in schooled girl that they have forgotten at the back and say 
"There. Do you believe me now. This is my boyfriend Hoseok and as you can see there's no way in hell that I would ever cheat on my beautiful angle and the love of my life so excuse us we have business to do."
He grabbed Hoseok's wrist and pull  the boy towards where he put his motor . He put the helmet on Hoseok and took on his to. He got on the bike and Hoseok followed him. Hoseok hugged him from the back and rubbed his face against Hyungwon's back.
"Ahh I miss this feeling so bad. And hey, I'm staying here in Korea and I'm going to go to your school so please take care of me ~ "
Hyungwon chuckled at his boyfriend's cute action and started the engine and went straight back to his house. They spent the rest of the day cuddling and telling each other about the things they have been through. And the following day, everyone in the school was in chock to see Hyungwon holding hands with Hoseok and smiling at him. They would never even in their wildest dreams would they think that one day Hyungwon would be caring for someone.the two love birds that finally got back together didn't even care for a thing and went straight to their locker and Hyungwon kissed Hoseok on the cheeks and that made the blond blushed and hit him in the arms. Ever since then they finally believed that Hyungwon was taken and that he loved his boyfriend more than anything and they even became the most popular couple of the school. Though sometimes people would see some person asking Hyungwon for a date and got not only a rejection but a jealousy  look by Hoseok or someone would ask Hoseok out. Sometimes it's a girl but there were still times that Hoseok got an offer from a guy too because of his feminine and cute but still not that girly of Hoseok. And every time that happens Hyungwon will pull Hoseok into a kiss to mark his possessions.
