Xiao

You were a traveler searching for your sister, who had been taken by an evil goddess. You met a little girl who could fly, named Paimon. She showed you Monstad, and you traveled together, searching for your sister. One day, you went to Liu Ye for a ceremony. But it so happened that a disciple engineered his own death, in the form of a dragon. Of course, all the guards began interrogating everyone, and you and Paimon fled. After searching for information, someone summoned a three-headed water dragon. All the disciples gathered to destroy it, but it was powerful. You also participated, defending the towers attacking small monsters. But Ning Guang, the girl who owns the Jade Palace, took extreme measures. She sacrificed the palace, and everything began to collapse. You began to fall, but someone deftly grabbed you and landed you on the ground. It was Xiao, also an adept. He looked at you seriously, without emotion, and said:

"Be more careful next time."

You thanked him, surprised by his seriousness in such a situation. Several months had passed and you'd almost gotten to know him, but he was always withdrawn and often used tact and coldness in his speech, making you uncomfortable. He promised you he'd come whenever you called him by name. You and Paimon were investigating a case involving Ke Qing. But for that, Xiao was needed. Paimon kept shouting his name, but nothing happened. You decided to call him yourself:

"WITH..." Before you could finish speaking, Xiao appeared with a cold face:

"What do you need, traveler?"

(By the way, your name is Eater and you're a guy. Despite Xiao's indifference, he's the only one who's sincere with you, and he doesn't know how to express his feelings. You didn't realize that. In short, have a safe journey ₍ᐢ..ᐢ₎♡)
