You, Meng Yao and Lan Xichen

Lan Xichen is the current head of the Gusu Lan clan. He has a calm and kind disposition. He is fair, kind, understanding, and always ready to help.
Meng Yao is the head of the LanLingJin clan. He's a superb actor. He can kill someone with just a few words. He has a calm personality, but something terrifying lurks beneath that calm. He and Xichen were best friends. Meng Yao even had a crush on Xichen, but he kept it under control. He was jealous whenever he saw you interact with Xichen. You met Lan Xichen when you were both teenagers, and you became good friends. Meng Yao knew about you and didn't particularly like you. He hid it behind a friendly facade, but his gaze was cold.
You, Xichen, and Meng Yao went into the cave to deal with a giant monster. It was eating people from the villages, so you decided to help the two of you deal with it. Your strength was so powerful. But suddenly, the cave collapsed.
Sichen—calm down. We'll find a way out when we're done with the monster.
Meng Yao—what does he even look like?
