Oh Sehun doesn't talk much. But when he is with his friends, he will be a total opposite person. He will talk like there is no tomorrow.

Oh Hayoung is the same as Sehun.

The difference between them is just that Sehun is the calm one and Hayoung is always the anxious one.

Sehun falls in love with Hayoung at the first sight. He himself doesn't believe that he is in love. But 

then he realize that he always tries to make lame excuses just to meet Hayoung.
