I read this cute yaoi before, I believe it was a oneshot. It's a student-teacher relationship. The uke leaves a piece of origami at the seme's office. The seme just collects them at first. Eventually, he unfolds one of them and found out each origami has a message, "I love you" or something like that. That is all I can remember.

I've been trying to find it, but no luck~ Please help me 🙂
