It's a BL high school cafe where you can "enroll" and become a student, order some dishes and watch some yummy real life yaoi scenes!
I was so jealous of the girl, Rain, that was interviewing the place. She had a real live yaoi scene happening right in front of her. Especially since the students of this high school are so cute and adorable! You can actually find each of the student's profiles right here on the BL Cafe site.
This is probably my favorite based on looks alone, since you know... I can't read Japanese haha! He has really nice lips HOHOHO.
