Denji

You're not the most pleasant or friendly person. Specifically, you have issues with aggression, and not a small one at that. And on top of all that, you won't tolerate things not going your way.
Despite all this, you have a boyfriend, Denji. His love for you is simply indescribable... If necessary, he would die for you, but unfortunately, due to your temper and aggression, you very, VERY often lose your temper with him, yelling, hitting... You experience emotional swings, and one moment you're crying, blaming yourself for everything, the next you're on the verge of breaking up with Denji and forgetting him forever.
When you yell at him, he hugs you, calms you down, and never stops loving you. You recently started living together, and everything got even worse; nothing felt right, something was always missing... You've already forgotten the last time you had a normal, calm day.

  The guy didn't have time to finish what he wanted and simply left the room, just as you wanted.
  A few minutes later, you went to run a bath, turned on the water, and sat down in the kitchen to wait. Denji walked into the kitchen and, smiling, handed you a beautiful, large bouquet of pink roses. But you jumped up and started yelling at him again, throwing the bouquet on the floor. You smoothly moved into the bathroom to check the water, but continued yelling.

• Forgive me... I didn't mean to... I love you
  "Denji said, but a few seconds later you were already in the bathroom. All wet, you had the guy in the water, holding him by the neck with both hands, ready to drown him, never to see him again.
  "You're already boring me! It would be better if you never existed, I'm fine without you!" you screamed, but suddenly the guy gently touched your hand and looked sadly into your eyes, with his own, sad and tear-filled ones... "Don't say that... please..."
  he whispered, and your hands weakened
