oh sh wait is the one on steam paid
Sorry, but I'm not sure I understood your message. If you're asking me whether this game is on Steam, no, I'm afraid it's not. Not yet.
If you're referring to United by Love's Heart, then yes, that game is on Steam:

Oh, yes, Project Yuri will be a paid game when it's released on Steam, although it will come with a demo to help you decide whether it's worth it or not.
If you're asking about United by Love's Heart (sorry, in the end I wasn’t sure which one you meant), it will have an early access version that will cost money, but there will be a demo that will keep getting updated, and the final game will be free.
