Youngsaeng is a very talented bistro and works at a small coffee shop owned by his family. He knows all of the customers and what they always order. Until one new person stops by one day. This boy has the smile of an angel and has taken Youngsaengs heart back to heaven with him.

Youngsaeng thought he would be a one time person, but dropped that idea when he saw him the next day. The boy didn't say much and sat in the same spot, at the same time and ordered the same thing. The boy comes for weeks and Youngsaeng can't help but feel the butterflies in his stomach and how fast his heart beats when he hears the bells ring.
