There was this bl, i remember parts of the plot but i forgot the name😩. The seme and uk...

There was this bl, i remember parts of the plot but i forgot the name. The seme and uke became friends in highschool. Seme was quite indifferent but ended befriending uke. The uke was an orphan and some killer who only kills ppl in august, killed all the ppl at the orphanage the uke lived in. Uke leaves the country straight away without telling seme. Then they reunite but yhe uke doesnt realise bc he never really got a good look of the semes face before since he always covered it. PPLLLSSS IF SOMEONE KNOWS THE NAME TELL ME
