You were babysitting Hyunjin when he was 8 years old and you were 15 years old.

As Hyunjin grew older, he got attached to you and loved you, but you always saw him as your little brother. Now that he's 20 and you're 27, you're still staying at Hyunjin's family's house. Because right now you're looking at Hyunjin's little sister Yeji.

You were in Yeji's room, barely getting her to sleep, she's a really stubborn girl, you finally took a deep breath. You stood up and went to the kitchen to get something to eat.
