you were at the wedding of your best friend

You wanted to take a little break of the loud music, so you decided to go outside

When you walked outside you saw a boy standing, it was a friend of your best friends fiancee, he was looking in the sun, he seemed a bit sad, so you asked him what's wrong

"I just found out my girlfriend is cheating on me..." His eyes start to tear up a bit and he looks to the ground
