It's princess maker (or slay the princess might be more modern) you pick your horses schedule and try to raise her various stats for the races without injuring her, in between you get little VN event scenes that you can make decisions in that give you different stats, the different scenes are decided partially by your scenario and horse and partially by a deck of support cards you build (the support cards also have different stat effects they give you), which is the gacha portion, the horses themselves aren't that rare so you can pretty much guarantee getting the girl you want there's a lot of tickets in this game for sparking but what you roll on is the support cards since they can massively increase your stats

This also means that if for some reason you're grinding the meta your runes will be 99% the same once you get the optimal deck set up, however I think this is one of the best games to play just casually for waifuing because you can change your cards out for your favorite girls and essentially have a very remixable unique vn each time
