"If she really loved Gojou and wasn't a hoe then she'd want to only look good for him instead of deriving delirious ecstasy from bathing in the attention and lurid gazes of hundreds of random nerds.
No wonder Gojou is disappointed."

"it is NTR because she's showing that she enjoys more and feels more validated by and values more the leers and gaze of random comiket otaku than she does him looking at her."

"Imagine wanting to help a bajillion digusting otaku freaks oggle your woman and letting them gaze upon the intimate glares and facial expressions that should be only for you [...]
wanting to help your gf become a famous cosplayer with hundreds of social media and IRL stalkers and taking her to places where she eye-fucks the cameras of every person in a crowd of people like she's their personal model is gross
I can totally understand why he's grossed out and feels like he's made a huge mistake.
It doesn't reflect well on her that she's happy making those kinds of faces with the cameras of hundreds of strangers. She should find it weird, like a violation to simulate intimacy with so many weirdo strangers.
If she really loved Gojou then she should want to only make those faces for his camera tbh."

"
Reminder that the reason why Gojou is disappointed and deeply uncomfortable around Marin is because he's seen what a slut Marin is and how much she loves bathing in the male attention of random nerd losers , how much delirious ecstasy she was in making outrageous bedroom eyes at random men, the kind of intimate eye contact she should only want to give to the man she loves, and serving as their masturbation material.
No wonder he can't even look at her the same way.
I'd feel sick to my stomach too."
and Gojou agrees with me.
Marin was being a fucking slut and he called her out.
you can all react to this post but you can't deny that this is what what Gojou himself was feeling. He admitted it. It's all there, black and white, clear as crystal.
