This game is relatively straight forward, but it is incomparably grindy.
The game is your average trainer and revolves around a doctor becoming infatuated with a girl while waiting for the early morning train to commute to work. Like how every other Japanese train is, it's very crowded, so the doctor ends up behind the girl. He has two choices here: rape the girl or don't. Well, its not actually rape... yet since the doctor is just committing sexual assault since he has no spine. Due to that, you have to sit through hundreds if not thousands of clicks while using the most optimal strategy to min-max the sensitivity gains just to actually screw the girl. And, don't get me started on the incredibly slow, un-skippable, repeating dialogue and transitions. Therefor, you are looking at a clicking simulator of a game due to the right hand (or left hand) exercise, I'm sure you all can handle it.
Additionally, the game has hidden values for excitement and alertness which are parameters used for the rate at which the girl refuses sexual advances. You can roughly estimate by referencing the girl's character sprite.
What makes this game particularly bad is that you don't know how much progress you have made until the end of the week so you don't know if you are wasting time by grinding this sensitivity stat which already got maxed out 3 days ago. The terrible translation is honestly somehow worse than AI with constant mix ups between gender pronouns. Not to mention, there are untranslated UI, so I had to use google translate to understand what I was supposed to be doing which also adds to the confusing aspects of the game.
The sex scenes are quite generic with 3 basic scenes (BJ, vaginal, anal), a close up view panel, and an xray for penetrative scenes.
There are 3 endings to this game all of which require a separate playthrough just for one: Fallen, True, and Normal. The plot is not worth your time nor is it life changing but that probably doesn't concern you since you are just here to indulge in sexual fantasies.
I acknowledge that the game dev is very skilled as every part of the game is original made without any rpgm assets. Which begs the question, why did they decide to make this game in rpgm??? The UX portion of the game is almost non-existent if not for the skip day button (which doesn't skip the unneeded dialogue).
Don't download, its mediocre.
