This is about a teacher, Fujiki Tomo, whose class has a new student who is as cute as an angel: Shiina Kazunari. But whenever Fujiki sees something unbelievably cute, he can't help but have an incredibly fierce and scary expression on his face due to nervousness. This scared Shiina a lot... and just when Fujiki is trying hard to fix his problem, a second "Shiina Kazunari" appeared in front of him at night. He stole a kiss from Fujiki, and said, "I fell in love with sensei today, and couldn't help but come and see you."
