People talking about how Ishigami acted like how most people realistically would are talking out of their ass. I mean its obviously realistic for Ishigami, but I wouldn't even fill up a whole hand if I counted how many people I know who wouldnt jump on a chance with a one night stand with the person they love. This includes me, lol I've literally done it before so this isnt something that crazy for me to imagine.
Ishigami is the ideal boy tho so it makes sense he wouldn't be down for meaningless sex, even if he regrets it later every time he thinks about it.
This also makes you think about how many other dudes she does shit like this with if she's so easy. Bruh she literally said it was a "Reward for liking me" Like bro what the fuck?! Who says shit like that?? Just say you want to fuck like everyone else does
