He would then noticing you as both of you locked eyes.

???: *in a bit of serious tone* Who are you?

Ema would rise a brow at who he was talking and look over and was surprised to see you.

Ema: *holds her hand* Wait, Jaylen! At ease, they're a friend.

Jaylen: *would blink a bit before smirking friendly* Oh my bad. *rubs his hair* I didn't know that. So in a least serious tone, who are you?
