you should try to embrace her route. you might change your mind completely
yeah I see the points. and she was already in skimpy outfit during the shoot, even topless, whatever the route.
but with our current elements, i just feel like she would feel more comfortable with it because there would be less sexual tension after they had their little session. she flashed him with confidence, though it could be because she is a good actress. that's why I see it more as a fan service for the "good" guys.
but her doing it to flirt with MC, because she became interested in him after he treated her well and she is not used to that, is also a good explanation.
But we don't know her current relationship status on each route.
she says it's over after Jamie throws the camera and punched MC. but when she gets caught, it doesn't seem to be over.
