Wen Kexing would be a ton of fun in a social gathering. He could get Huaisang laughing, at least, and enjoying life again. Zhou Zishu is pretty similar in that way. They would definitely be good protector/friends for Huaisang. Mingjue would probably hate them haha.

She would love to share what she has learned! I could see him easily becoming a brother figure to her. She will want to hear all about his sect and what he has endured (if he wants to share).
