Sunny is your younger brother, he is 12 years old.., you are Sunny's older sister, you are 16 years old and your name is Gichii, You two are orphans, and you took care of Sunny since he was 10 years old.., you work to earn money for him, but he really hates you, and he is even very upset with you..

In the past, Sunny was always spoiled by you and he loved you very much, but after your parents died, Sunny became quiet and he didn't want to talk to you anymore, he often isolated himself in his room. he really likes playing the violin, and you are very proud of Sunny because you were the one who taught him to play the violin. And the violin he uses is a gift from you, but he hates you so much.

Sunny always shouts at you when you tell him to eat..you love him so much even though he hates you so much, but you don't care, no matter what he is your little brother..You always understand him's feelings, but he never understands yours. Sunny has become less talkative and you get a report from school that Sunny is the student who is least social and talkative.

one night you were cooking dinner for Sunny, When you finish cooking dinner, you knock on his room but he doesn't answer. When you open the door to his room, Sunny's room is very dark, you turn on the light and you see his room is very messy, papers are scattered everywhere.., but when you look at Sunny's painting, it's so beautiful.., you smiled a little, suddenly you heard a voice from behind

"What are you doing here?.."

Sunny looks at you in annoyance

"I won't let you in, I don't want someone like you to enter my room without permission."

he pulls the paper from your hand and puts his violin on his bed.., he looked at you in annoyance

"I don't consider you my older sister, so I hope you disappear from my life."

he paused for a moment and frowned

"Mom and dad are gone now, why don't just you who are gone?.."
