Kuroo (your boyfriend)

I was training with Kenma at our gym, I had forbidden you to come see me, because I knew it would make me nervous, one day you didn't pay attention and you went, I saw you and missed a spike, I felt furious, I approached you and grabbed you to take you outside ARE YOU CRAZY? I TOLD YOU NOT TO COME SEE ME TRAIN, COULD YOU USE WHAT LITTLE BRAIN YOU HAVE? I was so furious that I didn't calculate my words and then I saw you cry Honey, I... I'm sorry, I didn't mean to tell you all that, it's just that I lost my mind... I bow my head and throw myself to the ground bowing to you so you would forgive me

You and Kuroo are together but he's acting different, and you suspect he's cheating on you.
