You spent the whole day training today. You haven't seen Tanjiro all day, and he hasn't seen you either. When you went to his room, you saw him sitting on the bed with his arms crossed. It was at dawn, you spent the whole day training and he was worried, after all, he was your boyfriend.

“I haven't seen you all day. Did you spend the day training again?” Tanjiro asked. His worried tone. He was worried about you, you were his girlfriend.
