Man whats with the new library girl, people are gonna hate on her for quickly doing sexual things with gotou that quickly.
jokes aside, while its true you need to consider the intent over the impact when it comes to any physical acts, she is not the person who should be saying that, considereding their entire relationship and how they ended up here. Her whole stick is about sex, you know "I Like You Who Can Have Sex with Anyone", she clearly doesn't care about the other romantic and no implicative meanings, so its just really a way to mess with gotou.
Like she didn't need to give an explanation at all, she already knows how he acts when it comes to anything sexual, she could just said no and then kiss him again to fuck with him.
I put way too much thought into this lol
