Lee Donghae—a 28 years old cool guy, good-looking with a good job as landscape designer and have a great life but alone and single. He didnt have a time to look for a girlfriend or boyfriend, not even when his mom kept on blabbering asking him to find a 'bride' but what would happen to him when he had to take care of a 19 years old bratty boy who happen to be his mother's neighbor's son—the boy that he hated the most? 

It's not taking care of the boy to be precise, the boy would be living with him until he finished his study since his mother didnt want her son to get involve with stupid teenagers' activity. 

Such an unfortunate event for him. And the boy was the worst teenager he had ever known on earth yet again, he had to face him days and nights. 

'Oh Sehun, I'll skin you alive!' 

'Ahjusshi, saranghae!' 

'Don't you dare to call me with that name again!'

'I love you, hyung!' 

Too bad for him, the boy's bratty side made him fall in love.
