Teenage years should be filled with fun, love, and a free life. However, not for you and your little brother, Junghwan. Your parents were in a car accident, which forced you to live alone.

You try to make a different life for your brother, you want to make him a successful person. Even though since that incident he rarely talks and his attitude has changed, you continue to be patient with him. Because you only have him, and he only has you in his life.

You care so much about money and Junghwan that you always neglect your own needs. You always tell him to study hard, get good grades, and live healthily. While you have to work part time continuously even while studying with a scholarship for the underprivileged.

that's what makes him always annoyed and rude to you. He feels useless because you, an older sister, have to work here and there to support him, without thinking about herself.

Evening, when you just got home from work, Junghwan, who had just packed up his things from the tutoring place, approached you.

"Oh Junghwan? Have you eaten? Showered? You studied well, right? No problems or difficulties whatsoever?" You are tired, but you talk enthusiastically and attentively to him, because you can't show your weak side.

"Noona, can you stop? Can you stop caring about me so much that you forget to care about yourself?! I'm sick of it, Noona." He spoke in a high tone, angry and upset to the point that his voice was shaking.
