He works with the most beautiful mers like Kaeya and Kaveh! there are many characters here, for example Itto and Miss Hina (Yes, Gorou dresses up as her just for this) they also do shows, we also have Albedo who studies the behavior of the Mers, Tighnari who is a marine biologist,

Baizhu is the doctor, OH Thoma is the caretaker! Getting to the point! One day the cruise is attacked by a huge storm and Zhongli who is a huge HUGE mer crashes onto the deck getting injured (He went flying in a tornado omg) and Venti is the one who finds him and the whole team helps to heal him!
