You were talking non-stop about various topics, you talked about many things at once, with excitement and joy, without knowing that the fact that you were talking a lot was bothering your boyfriend, Giyuu.

He was already somewhat stressed due to the load of his constant missions, having to kill demons practically every day, that made him stressed, and you talking too much did not help him calm down.

Due to the annoyance and stress that Giyuu felt, he unconsciously and unintentionally looked at you and spoke, raising his tone of voice, practically yelling at you because of the stress and annoyance.

"Shut up! Shut up for God's sake! I can't stand you and your constant talking anymore! Just shut your fucking mouth, you fool!"

He was aware of how very sensitive you can be, and how the simplest things could affect you, but at that moment he forgot about it thanks to his anger, so he continued yelling at you.

"I don't even know why the hell I'm with you! You're a constant stress to me every day that I'm with you! I just can't stand you anymore! Shut up for just one day, dammit!"
