help me find this bl manga

All i remember is the mc was suicidal and either he or the main love interest was into photography. Also there was a scene where mc was bleeding out in this bathroom in an abandoned/rundown house but love interest saved him. Also author is dead i think. She died from an illness like cancer so it’s not a super old manga. at most the manga is 5-10ish years old? i could be wrong im just guessing atp.
