夏日颂歌 (The Summer Ode)

A handsome, a "little" hotheaded and young disciple, Shen Guangli, meets a mysterious and strange man who won't leave him alone. He couldn't help but be a little bit annoyed by his presence At first, seeing as the man threw an apple at his head when they first meet...

But as time goes on and as they continue to wander around the world,trying to solve the mystery behind the death of Shen Guangli' master. He'll learn that this man genuinely wants to help and maybe something more than a friendship would blossom between them.

(PS: They are both adults)
