Sooyoung, a premarital chastity advocate, is the wealthy young master of a so-called third-generation chaebol family.
Though he faced various dangers(?) growing up, he held fast to his beliefs.
One day after returning to Korea, he sees Ha-joon at a party and falls head over heels at first sight.
He hadn't intended it, but when he came to his senses, he ealized Ha-joon had completely taken his virginity.
Just as he was thinking about dating Ha-joon, marriage, and even children, he wakes up the next morning to find the spot next to his in bed empty.

So he goes to Ha-joon's university main gate and boldly declares...

"I! I've been taken, so take responsibility!"

But what do you know? Ha-jun cleanly rejected him, saying he wasn't into chaebols.
He's not into rich guys? What the hell is wrong with his taste?!?!!
