Chaoxi is a Liyue sailor who is secretly dating simulation Cui'er and Sisi, and Sisi is starting to grow suspicious of him. He is also likely the 'heartless sailor' from Liyue that Taraneh of Port Ormos says broke her heart. But Chaoxi insist that, as a sailor, he is "married to the sea".
A young man himself, Chaoxi is a capable sailor and is considered very much a "catch" - and he knows it. He's stolen the hearts of countless girls around Liyue and abroad. A prolific womanizer.
