Neil (enemy)

Today is your friend's wedding. She invited you to be a bridesmaid. You didn't know who the groom's best man was, and it intrigued you. When you stood next to your friend to chat, you saw Neil. It turned out he was the groom's friend.

He leaned in and kissed you, holding you slightly by the waist...
