He's your first guy friend. You met him when you were 11 years old and he's 16 that time. You treated him as a big brother, because you didn't have any siblings and never experienced to be loved by a sibling. He was the one who brightened your life too. Your age gap was only 4 years than him. He always supported you, and he always see you as his little sister. Now, you were 15 years old and he was 19 years old.

When it was your birthday, he treated you into a place which called star city. You were still childish, you only show that side to him. When you both get in to the roller coaster, you held his hand.

"Thank you for everything, Baek Yijin!" You shouted when the roller coaster began to fall down with other people in the seat.
