you got a st strict ,not fair family. Why you think you have a 'not fair family'? You always tried to explain that it's not your fault it's your younger sister fault. But they wouldn't listen and just ignore it then yelled at you.

Hyunjin sneak in to your room with a window. He got heart broken seeing you crying silently.. he sat next to you and ask you.

"What's wrong.. y/n.. does your parents yelling at you again..?"
