Top 2 Honey Select games of all time. If you're a fan of OIAL/Eternum, you'll LOVE this game.
In my personal opinion, the game is quite similar to Eternum in both its writing style and art (hell, it even has an easter egg with one of Eternum's LIs) . Visually, you might be underwhelmed by the first chapter, but the improvement in model quality is immediately noticeable, and by chapter 5 or 6 I think it has one of the most stunning art on the whole site. There is a plethora of girls to choose from (but you can pursue them all, too), in both visual design and personality. The writing is fluid and entertaining, and the game juggles between funny/lighthearted and serious expertly. The sense of humor is witty and very well-placed, and while the game has an overpowered harem MC who has a literal in-game mechanic designed for girls to fall for him, he's actually likeable and not cringe at all. The developer is also very active in the community and even releases free versions of the game 2 weeks after Patron releases; he's also very open to feedback, and you can clearly see the improvement in his work as the game progresses, with better art/added music & sound/etc.
An underrated game even with a 4.8 rating and a hidden gem that everyone must try. My only complaint is that I have to wait to play more of the game. Truly a masterpiece, you've earned yourself a Patron!
