My classmate Yuri has a boyfriend. He's an older college student. I was always attracted to older boyfriends, so I was just jealous. Today was the day I was going to hang out with Yuri at his house. Naturally, the two of us had a great time, and started to get cozy in front of me. But for some reason, I found myself feeling jealous of Yuri. What should I do... I've fallen in love with him, even though he's my friend's boyfriend.
