Ah, where there are innocent and cute young men there will always be older rich men who love them secretly from the shadows and support them anonymously.

The students always call him dark, dirty, scary so science teacher, Fuwa Tsutomo, couldn’t show his true identity as a good-looking man. Yet he had liked a student, Kurusu, who was failing science. So in order to help and be with Kurusu, even if it’s just for a while, Fuwa changed into the “Phantom of Science” and be a private tutor for Kurusu. Unfortunately Kurusu’s friend revealed his secret, but still Kurusu didn’t care; he only hated Fuwa, not his “Phantom”.
