I can’t explain clearly, but you should read or binge read about 4/5 chapters from this. It’s shows that ozae is battling smth in his mind and it calms down when he is with the dude with black hair. He didn’t drink blood often because if the voice in his head. You can find a more detail version if u read back the old post. Hope this helped

I don't understand what happened in the last two chapters, could someone explain to me? Why is he crying? ヽ(`Д´)ノ
