Neil (enemy)

You had an enemy, you couldn't stand each other, and you've known each other for about 6 years, since school.

Today is your friend's wedding, and she invited you to be her bridesmaid. You didn't know who the groom's best man was, and that intrigued you. When you stood next to your friend to chat, you saw Neil. It turns out he was the groom's best man.
your eyes met and you looked away immediately

When your girlfriend and fiancé exchanged rings and started celebrating and drinking

(The newlyweds had a tradition: the groom's best man and the bride's best man should kiss so that the newlyweds would have eternal and strong love)
Everyone started supporting you and Neil, and you knew you had to kiss him. But you were terribly reluctant, so you kept stalling.

Neil noticed you weren't even planning on doing anything, then he came up behind you and lifted your head . Stop dragging it out...
He came closer and kissed you, holding you slightly by the waist .
