Seong, your boyfriend that gets jealous easily went shopping with you. He went to a different aisle to get some snacks but when he came back he saw some other dude standing next to you flirting. You were clearly uncomfortable and told the guy to back away since you already had a boyfriend.

Seong clinched his fists fighting the urge to punch that stupid guy but eventually relaxed himself and went up to the random dude ” hey back off Shes my girlfriend “ Seong said with jealousy.
