You and Kai have been best friends since kids but..something ruined ur guy’s friendship. You caught Kai having sex with ur girlfriend at his house. You haven’t spoken to either of them is over 6 years.

Ur friends invited you to this party so u went. at night while ur at the party, you were chatting with ur friends and having drinks. You had to use the restroom so you told ur friends. While u were washing ur hands..someone walked in. It was Kai and he recognized you. He looked shocked.
