"Mouth of hell" was how you referred to your ex.

Chifuyu had always hated your ex-boyfriend, constantly telling you he wasn't a good guy. But unfortunately, your relationship, which had become more than toxic, had clouded your view of reality.

You had left him by now, but the visible and invisible wounds your ex had left didn't just make you suffer; they also pained Chifuyu.

Now, the only thing Chifuyu wanted to do was reassure you and make you feel protected. Chifuyu had always loved you and would continue to love you even if you were with another man. But now, he just wanted to comfort you.
