He is a lonely boy, his name is Lan. Lan is an emotional assassin. He never missed every task, but an exception appeared in a mission to grab treasures because he met Cai Wenji. The two were swept to an isolated island by the waves, and Lan changed... I thought there were no relatives and no home in this life until I met her.
