Most reviews focus on gameplay so I'll focus on story while only briefly mentioning other aspects. To keep it short though, I don't know if it's worth playing without the sequel existing to conclude the story. If you have a lot of time to kill and are fine with shit endings or have no regard for story, then go for it. The porn is great but (and this might sound weird for an h-game) you can't rely solely on the porn.
Gameplay - Its alright but could've been better - The pinball portion is great, the dating sim aspect is good enough, and the business management part is a boring chore. It feels like 3 separate games with minimal cohesion.
Artwork/Hentai - Damn son, it's really good - Visually appealing and the h-scenes make excellent use of the various locations. Unfortunately, the "sex progression" could use some work as in some parts of the game the girls are a bit too quick to hop on that dick. Regardless, it's incredibly enjoyable.
Quality of Life - There's one negative that needs mentioned - Excluding pinball and a much later management fast forward unlock, this game is slow to the point where it becomes annoying. QoL unlocks are too little too late as it takes too long into the game to unlock them and they don't solve all of the issues anyways.
Story: Overall - Has the recipe for success but fails to bake the cake - I'm issuing a spoiler warning for the story sections of the review! I'm going to break it down into three major parts.
Story: Main Plot - It's irrelevant - The main plot of the game is irrelevant outside of the beginning and ending of the game, which itself is failure of storytelling. There's not much else to say about that, it's inexcusable even for a hentai management game.
Story: Character Stories - It's alright but something is missing - These are explored during the dating sim aspect of this game and is the actual story aspect of the game. The development during the dates feels like there is genuine character exploration and connection between the girls and MC. The issue is that nothing carries over from the dating sim gameplay to the business management gameplay, and since the main story is dead in the water there is no joined progression on that front either. Your progress with each girl during the date is irrelevant when you're wooing her during her massage so things feel disjointed. In addition, after all h-scenes there is brief dialogue between MC and the girl(s) in which they decide to keep the sex a secret or MC doesn't inform the girl that they drunkingly fucked in order to actively avoid developing this aspect of the story. So there's a lot of character story, but it doesn't feel like there's any payoff.
Story: The Endings - Somehow they're the worst story aspect of this game... the ending(s) to a game with an insignificant main plot - This game has an outright sad ending that is used to set up a sequel. There are three glaring issues with this conclusion. First, it throws away all character progress with the girls in the final moments, literally having them say goodbye. Each girl's development is character exploration and character connection, not bettering the girls as people but developing the girls so they are reliant on MC. Therefore, all of their development is thrown away as their ties with him are severed, logically they'll regress to prior form. Additionally, yes as I said their stories don't really link together during the game but as players we experience them, so while the game doesn't make those links we ourselves do. Yes this is a h-game and we're mostly here to jerk off, but that's no excuse for making the player's efforts pointless. Second, this game comes off as a game of building hope, so the sad twist at the end is straight up out of left field. It literally has you build up character relations for the sake of making you sad. Bro, why? Third, and I've noticed this with a lot of h-games recently, it makes the game inconclusive in order to sell a sequel. Devs, please stop doing this. By making the game inconclusive you do more harm for my interest than good for both the sequel and current game. The first game in this series came out in 2023 and the second (this game) in 2024 - a remarkably quick sequel - but whether the turnaround time is 1 year or 10, it's irrelevant for an h-game. Stop sacrificing the present in hopes for a better future.
