Please Help Me Find This Manga

It's a yaoi manga about a PE teacher where I think in Valentines day, gives all his students chocolate and one condom and at the end of the day the students... *ahem* fuck him *ahem* one by one.

i'm about to lose my mind. can someone please help me find this manga where the seme is some non human being and he protects uke until the uke gets his soul stolen (or got broken idk i've forgotten some critical details) and then entered this vegetative like state. in his dream he met this woman that looks EXACTLY like him wearing a white kimono (which he thinks the seme previously loved), cue some misunderstandings and yadda yadda. ARGH, I'VE FORGOTTEN SOME IMPORTANT DETAILS. but please, if you know some manga that has a plot similar to this, do tell me! i want to read it again. :^(

something i vaguely remember: uke can see supernatural beings.
