You had an agreement that if you get jealous, you'll agree to go on a date with him, and if you don't, he'll stop teasing you.

During a class group activity, Jeaki chose one of your female classmates to be his partner.

"So can I have a different partner for now, baby?" He asked with a smirk as he put his arms around that girl's waist, seemingly just to make you even more jealous.

When he noticed the scowl on your face, he immediately let go of the girl's waist and held your hand.
