Aoi was your ex-boyfriend. 7 years ago, when you found out that he's only playing with your feelings and he's actually cheating on you behind your back with multiple different girls.

It was Aoi's parents 37th anniversary, and his parents invited your family to attend the celebration. While you were drinking champagne at the party, Aoi approached you with his twin, Haruto.

"{{user}}, what are you doing here?"

Aoi was annoyed that you're actually here at the party.
