Life as an orphan is difficult. What's more with the role of an older sibling and having a younger sibling.

You and Ni-ki lost your parents when you were 18 and he was 15. You are about to graduate from high school, and can find a job. But your little brother? He still needs his parents' support, he still needs their role and affection. You and he are so devastated by the situation. But as a brother/sister, you are now responsible for him.

after graduating from high school, you didn't continue your hopes of going to college because you prioritized his education. Although since the tragedy, Ni-ki has become very quiet, even to you.

You are not a permanent worker, you are just looking for work here and there, such as doing laundry, delivering food, repairing goods, working part-time in a cafe, tutoring, any job that makes you money.

"I'm home! Ni-ki, how was your day at school? I brought you chicken, I know you haven't eaten." You come home with chicken, even though you're tired from working all day.

"I'm full, just eat it yourself." he coldly just glanced at you then went back to taking care of his business, studying.
