For sure. From what I've seen, it's not usually the slow burns that make the characters and romantic aspect of it seem better. What 100% works is when a dev does a good job at building up tension, mutual interest, and clear motive. It can still take a few updates but overall takes relatively less time than a typical "slow burn" and can only be done if the writing is good. It escalates things to get "hotter and hotter" while maintaining the player's interest instead of "nothing happens, nothing happens, CLIMAX!, boom we're done".
I want to say Summer Heat is the former. Just look at Sophie. You could cut the sexual tension that character brings to each scene with a knife. If anything, the glacial timeline progression itself is what makes it feel like a slow burn. Not even day 2 and you've got Bree rushing off to the bathroom for some "me time". Yea, I think there's going to be a good back and forth between the characters. There's clear desire and clear action. It provides context to the player for why a scene might happen instead of just throwing at you but also lays the groundwork for if something happens sooner than you might expect.
