Typical japanise MC, "girl likes me, clearly it's a misunderstanding, shes being misleading by comming onto me", will this trope ever end? I really want it to end...
No, he's not dense. He's fully aware of how she sees him. A couple of chapters ago he even purposely let her witness how he fucked his hot demon friend/teacher to subtely make her realize, that she should give up.
Lmao, what was the point of these last 3 chapters. Even for generic filler drama, such as one-shot villians attempting rape this was just horrendously bad.
The correct interpretation is that MC thinks the girl only sees him in a platonic way and definitely not developing anything, and thus feels her manner of speaking was potentially 'misleading' if it was any other virgin boy at the heights of puberty she was speaking to.
Really wouldn't call a man dense for ignoring the advances of a lady, especially when he already has somebody and hasn't shown any interest in being shared.
