In his two years working and following his father's steps as CEO, Sunwoo had never been the brightest and wonderful person. The board of members hates him and people in his company are afraid of him. He only trusts his secretary. One night after accidentally dining out in a pub he was struck from the wonderful voice and features of one singer, Sandeul. 

Sunwoo hates Junghwan for letting him travel alone. But he writes him letters, he tells him his stories and he even buys him a rubberduck toy. Junghwan loves him despite the differences and incapabilities Sunwoo shares.
