Am I the only one who finds it weird that kento can ntr the mc when he has the smallest dick in the game.
Also still nothing on James.
It's not really explicit
how he seduces Rei, though it's assumed that he blackmails Rin (threatens to tell her husband), and Eris will initially fuck him purely to spite the MC. That aside, he's clearly way more experienced than the MC--he visits multiple prostitutes and has been doing so for a while. So even setting aside the fact that this is an h-game and he's an antagonist, it's not totally unfeasible that he puts on a better performance than "Tom," who is annoyingly timid and busts almost immediately when Rei finally gets him to make a move on her.
...back to how he gets with Rei: I don't get that either. There's a clear sense of escalation in the pictures as they progress, but Rei never expresses discomfort or curiosity about it with the MC or indicates that she's getting closer to Kento outside of their photoshoots. If they started spending more time together, if Rei brought up things that Kento did in conversation (asking if they were normal or if Tom would like it if they did those things together), and if there was a progression of their intimacy even behind closed doors before you can catch them together; all of that would make it less jarring and more believable when they do start hooking up behind the MC's back. As a bonus, if the MC simply fails to progress along Rei's route adequately it might make sense that Kento wears her down that way--Tom isn't interested, so she explores other options.
