Oh Doyeon

An omega named Choi Jaewon enjoys a carefree life abroad with his Alpha friends. When he returns to Korea after being deceived by his father to get some money, a marriage with his childhood friend awaits him - the Alpha, Yang Junhee! Unlike their childhood days, seeing Junhee now, Jaewon feels that he is Jaewon's ideal type, so Jaewon proceeds with the marriage. Jaewon promises something to Junhee, but Jaewon can't remember it at all. A sexual romantic comedy about Jaewon and Junhee soon begins!

He graduated early from the science department, acquired his PhD at a record speed, and is now a senior researcher making a large salary at a major company. In other words, Go Youngwon is a pitiful engineering student that has never been outside his school or the lab. Just like his name, he dreams about love and forever ever after. But, he’s actually a sucker for looks and falls in love quickly. Because of this bulldozer-like personality, he often gets dumped before he even starts dating. Meanwhile, the guy he’s been stuck with lately is... Kang Hyunwoo, a man of the same age, and who has the exact opposite temper, tastes, personality, and basically everything else.
