That Summer it wasn't Lu Xuan who had experienced what it was like to be in love. There was someone else too. Someone who had yet to realise that he had long blurred the lines between friendship and love.
Gu Shangyan opened the door of the cafe that he frequented with Yoona after the library. They had known each other for almost one month. They went from fighting with each other for every petty thing to fast fasts.
As he opened the door, he saw Yoona smiling at a guy. It was Sunday which meant he didn't have school. He scowled when he saw the boy making Yoona laugh. He didn't know what possessed him at that moment but he shut the door and walked out of there in a fit of anger.
Yoona's eyes fell on the door and she saw Gu Shangyan leaving. She looked at the boy who she had met in the library and recognised him as that friendly waiter in this cafe. She frequented this cafe enough to be friendly with the staff here.
