I loved that chapter. Nagatoro really doesn't want anyone else to touch her man.
I do hope that MC develops feelings for her, because it's kind of obsessive at this point. He hasn't really shown anything past thinking she's attractive.
I think this story's about her coming to terms with her life. Different characters represent different parts of herself or her past she's facing.
Mutsuki is her innocent self, about to be killed by the stalker, who is the man she planned to give her virginity to (and was raped by).
The child/boy...
I'm liking this arc. We're getting to see the girls in a different light, rather than just purely "I wanna fuck him."
Even if it's only briefly I like seeing them be playful and honest without other characters interrupting.
Akane best girl tho
