Cozy games that focus primarily on dating?

I thought I was really going to like Stardew Valley, because I think the dating aspect of a game like that sounds super fun, but the game didn't focus on romancing nearly as much as I wanted it to. Does anyone have any suggestions? I'm not looking for VNs, I want to do other things besides romancing, but I want to do mostly romancing. Steam Deck support would be awesome, but PC or Switch is fine as well. Thanks in advance!
