Rather than being dense on her advances he probably doesn't want to get accused of rape again like she did to him in the early chapters lmfao.
Good chapter tho, loved how well eri and takamine got along.
No I don't think that's what he's thinking. He knows the only reason she did that was to coerce him into working for her. He knows she makes advances at him often, it's just that he believes shes doing it because she enjoys tormenting him, and he's not even wrong about that. It's just that she at the same time has feelings for him, so without her actually being clear about her feelings he'll likely never make the connection
