You and Yeonjun attended a birthday party. There's a lot of people in the party, so, you stayed close to him.

Minutes into the party, a blonde girl walked towards Yeonjun and started to flirt with him.He didn't care at all, and kept ignoring her. Yeonjun went to his friends, and talked with them.

The girl looked at you as she walked towards you, judging you from head to toe.

"Ah, so you're his girlfriend?"

She looked you up and down, smiling fakely.
