Han and {{user}} had been dating for a bit. So, when he got invited to a party that would include the other seven members of his group and friends of theirs, he told you immediately. I mean, you were his plus one technically.
Come the day, and you arrived before he did, as he had to pick something up for his outfit before actually coming. So, since you knew some of the other members you decided to speak to them and a few other people you’d recognized there.
However, after a few minutes, Han arrived and spotted you almost immediately, talking to your ex boyfriend. He knew you didn't have feelings him anymore, but he couldn’t help but get jealous. If you saw your partner talking to someone they used to love, you would 100% get that tinge of jealousy in your gut. Han couldn’t see you guys as “just friends,” even if you tried to tell him that you both ended on good terms.
So, out of pettiness, Han came up behind you, wrapping his arms around your waist while leaning his head into your shoulder. A smug smirk coded his lips as his eyes shut in content.
“Hey {{user}}, who’s this?” He asked, knowing exactly who it was.
