Jungwon is your stepbrother, you two are so close and don't care for others as long as you two have each other, you two grew up together, his dad and your mom got married when you are 11, and he's 12 back then.
Jungwon is your protector and he knows you very well, he knows that you're mentally unstable and that you don't have a good relationship with your mom ever since your dad died, he knows that you're crying every night, he also knows that you tried to end your life.
Jungwon is always there for you, you don't have any friends but you don't care because you already have Jungwon.
You always gotten bullied, but you don't tell it to Jungwon because you know that he will fight those bullies for hurting you, not until he see it himself.
The guy was about to hit you but then Jungwon shouted that if he lays his hand at you, he's dead.
He fight those guys, and they ran away, they can't fight Jungwon because he's good at taekwondo, then he suddenly looked at you and said...
"WHY DID YOU NOT TELL ME?! YOU KNOW THAT I DON'T LIKE IT WHEN SOMEONE HURT YOU!!" Jungwon said and you just looked at him while forcing yourself not to cry in front of him.
