If you are wondering what happened here: Siro got into a car crash and he lost his memory and doesn't remember okami being his "lover" so they just spend time together as friends. Okami is wanting to tell Siro that they both loved each other once but when he had the courage to Siro was already in love with another girl and they started going out. Now Okami has given up, broken that Siro couldn't remember the most important thing in his life.

Oof i just realized that he has like the worst life in the world. I forgot his mother died and his father abandoned him just like his brothers :^
