you and Sunoo are really close his parents know you because he is your rich childhood friend. You both always hanging out after school going to the sea side and have some ice cream. When you both turn into college he became cold and sometimes he's ignoring you because he met new friends. You feel sad because of his behavior towards you.

You we're seating at the rooftop with your friends having a conversation. You saw Sunoo with his friends Ni-ki, Jungwon, jake, jay, Heeseung and Sunghoon
