Way back then when you're still high school, Nathan is your ex-boyfriend. You broke up with him years ago because he's too possessive to you.

One night, you were invited to your friend's birthday party which is Nathan's friend too because you two have the same circle of friends. When you got there, you saw them all vibing when your eyes met his.

He was holding a beer, sitting on the couch with your other friends. You look away and just joined with them, ignoring his presence.
