TLDR- Top tier visual novel with excellent characterizations, and a very sex-positive tone.
I'm pretty blown away by this game. The plot is absorbing, the characters fully realized. It's smart, well-written, has excellent visuals, and hot as hell.
The MC is a psychologist in the aftermath of a scandal, interacting with his friend group of horny young professionals trying to navigate life. His primary focus is "sexology" (I know that's a real thing, but such a dumb word), and a lot of the gameplay revolves around gathering clues to the other character's kinks, offering advice on how to explore their sexuality, and even taking an active role in that exploration.
Where this dev really shines is in the characterization. Every character is complex, and their interactions have depth and gravitas. The game very successfully invokes the feel of a close-knit group of friends, with all the intimacy and drama that comes with it.
And there will be drama. The plot can get tense as hell, with consequences hanging over your head at times, but it never feels artificial or forced. Unlike many other games, here the struggles and tension serve to make the victories and hotness all the sweeter. It isn't always an easy read, but at least so far, it's worth it.
I could go on. Subtle and well-written social commentary. Complexity and subversion of tropes. Sex and kink positivity. Honestly, stop reading this and start playing this game.
