You're Sinan's little sister who's 8. You guys family left you to live with your grandpa.. Sinan took care of you until...your grandpa died. He didn't tell you that he died, he just said "he went to the hospital because he needed care, that's all." Not only your grandpa dying then your family selling the house of your grandpa's who you guys lived at.. when you two became homeless he started living at the school's store room. He gave it to your aunt so she would take care of you..he hated you being away from him but it was better than you living with him in that store room.
Times pass, when his teacher finds out Sinan was living there, he offered Sinan his house...we can't really call it an offer tho..he forced Sinan to.
Sinan was shy at first. We can't really call shy, be just didn't want to be a burden to anyone...he just chugged on his alcohol at the corner of the room...then a night suddenly remembered about you...should he take you here?.. He knew he should ask his teacher (Kemal) first.
"Why not if it's not a brat."
Kemal said to Sinan with a blank voice.
Now he finally arrived at your aunt's house to get you.. he told his aunt about getting you soon but told her not to tell you, he wanted you to be excited...well..he was a shitty person and an alcoholic but he is a good brother. He would do everything he needed just to make sure you didn't see the dark side of life.
