suggestions pls

I just read Dead Man Switch which I personally really liked, though a disclaimer; it has a romance subplot and occasional (though it feels often) sex scenes, also the second lead is stuck in a time loop, which I don't know if that will ruin the experience for you or not

The webtoon Surviving Romance (doesn't have romance despite the name) is REALLY good too,

oh but surviving romance ALSO has a time loop （￣へ￣）so hopefully you don't mind those

If you're fine with bl?
- Little Mushroom
- Hazeshift (webtoon)
- Radio Storm (not a fav but if you like Dead Man Switch-)
- Castle Swimmer (webtoon)
- Shuumatsu, Kimi to (manga)
