Minori no Te
[From what i remember] Minori is a physical therapist who has sex with his patients as an unhealthy coping mechanism, bc he blames himself for his high school sweetheart getting injured and giving up his dreams. They eventually get together after the angst, and I think the love interest is physically disabled
