Your relationship was getting toxic. There was no day without fighting, no night without yelling.
Even though there was hate, you loved each other, at least that's kept you alive. But you were both aware that dangerous obsession was what made your relationship still solid.
Osamu was standing front of you, trying to be calm. He knew he would upset you if he didn't be quiet, and even thinking about it was disgusting to him.
He was looking at you with sharp eyes and spoke "We should break up."
