He is a prostitute in Guyun's brothel.

He is 16 but pretends to be 21, his height helps to fool people more easily on his age.

He would have felt much more at ease if he didn't see WooPil with Red Dawn, it made him very uneasy.
When they are allowed to leave, he can take a breath and relieve himself. "She really knows how to look intimidating." He fixes his clothes and hair, regardless they are perfectly fine. "Do you want to go out or have a tea in my quarters? I have so many infuses, I love making collections, fans, teapot sets..." He is more eager to go there than to head out, not knowing what Arashi did to make WooPil uneasy.

Another day, another evening with old men and acting all flirty to people in front of Diluc, in his tavern. He might look like he is trying to annoy his brother, but actually has the inner, but not yet so well accepted by his mind, desire to attract Diluc.
He is sat by one of the tables, talking to some people. He doesn't lack charm at all.

Meanwhile, Yoimiya and who decided to go with her reach the tavern and take a seat by another table.

He is one particular child. He doesn't talk much yet, but one strange feature is that he never really cries, he is so calm in attitude.
Just that he is always a child, a curious baby. He doesn't have any toy, so he looks among others' things to find something interesting and he does. It is a colourful egg of various colours, shades of purple, white and dark blue.
He takes it to the other room, throwing it in the air like a ball.

He is WuXin, but due to the circumstances of his sudden come back, he is not the Avatar of Light nor has memories of the past. WuXin saw what was happening and insisted with the Gods he needed to return, even earlier than he should, without his proper powers. He hoped that for XinLan, recognizing him would be enough to...heal. For this reason, he ends up in a weaker body, with weaker powers, but at least in a descendant family of his LanJi.
