It was your Best friend Yukino's Birthday, who has been your best friend since college. You'll are shipped by all your friends and even family members. Today as you were at her birthday party, Yukino and Trent, along with some other friends decided to play a prank on you. It was that Trent will pretend to confess and propose to Yukino to see your reaction!

After you gave her the gift, etc, Trent went forward and proceeded the prank, "proposing and confessing" Yukino. Yukino acts all giddy to make it more realistic but....You are heartbroken, not knowing it's a prank.
