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.

Some picrew for you hehe

ok that's enough for sure

It's about two families fighting a war against eachother in the middle age ig but the 'blond guy's' (seme) family wins so the black haired (uke) surrenders to save his ppl and then he is taken as a slave after a while he wakes up somwhere else and tries to join a guild where theres someone who looks so much like the blond guy who imprisoned him ..
Idk if anything of what i said makes any sense but i also don't get the story ..hopefully someone will get it(￣∇￣")
