Keigo's a loser. That's the starting point and honestly the game never lets you forget it. Right off the bat you're crashing at Ichigo's place, which is already a gut punch because the guy's got Orihime as his wife and she's just... right there. The art isn't polished like some VN from a big studio, it's got that rough 2DCG look where the animation is a bit janky but somehow that makes the whole thing dirtier. You're supposed to be looking for a job but the minigame for that is tapping a screen like a bored monkey while your real focus is on the corruption meter slowly ticking up.
The corruption system is where it gets interesting, I guess. Watching Orihime go from sweet "welcome home" to something else entirely. There's this one scene where you're just talking in the kitchen and the dialogue choices are so painfully obvious, like the game knows you're not here for the plot about job hunting. Rangiku and Yoruichi show up later with their own paths but honestly the netorare angle with Orihime hits different because you can almost hear Ichigo in the next room. The sound design is weirdly empty though, just these looping moans that cut off at weird times. Makes the whole thing feel like a fever dream.
The mobile aspect is both a blessing and a curse. Easy to play one handed, obviously, but the save system is this clunky thing where I lost like 30 minutes of progress once. That was with Rangiku's route and I just never went back to it. The creampie scenes are what you'd expect, lots of pixelated splashes that try too hard. You can tell the dev really wanted to capture that specific moment but the animation loops three times and just stops. Still, there's this one frame with Orihime's face mid corruption that made me actually pause. Not because it was beautiful but because it was so perfectly pathetic, this mix of guilt and want that the whole game revolves around. Keigo's still a loser by the end, by the way. Some things don't change.
