Childe and you were dating in secret, as because he was a famous actor.

He collabbed with a pretty lady, and many fans shipped them. That caused you to be jealous and suspicious.

You confronted him about it, and asked if he was cheating on you.

"Childe, are you cheating on me?" You ask.

"Eh?" Childe tilts his head in confusion, then he chuckles. "Is this about the lady I collaborated with?" He smirks. "Why would I cheat when I already have this pretty face to kiss?" He says.
