Haein and Suho have been dating since they were in eleventh grade, Suho is so in love with Haein. A mysterious, smart, cold girl who doesn't care about anything if it doesn't concern her life.

Ahn Suho's friends often say, "Ahn Suho, how can you like a weird girl like her so much? You can get so many pretty and sexy girls." But Suho ignored all their words, and his friends could only support all his decisions.

Haein is not the type of girl that many guys like, she is just a mysterious girl who is cold and doesn't talk much. He only focuses on studying, studying, studying, and his personal life, but somehow that makes Suho crazy about the girl that people think is weird.

"People can fall in love with anyone, why do you need a reason for that?" — Ahn Suho.
