Can I Get a Really Addictive Slowburn Rec?

I’m in the mood for a really addictive slowburn romance with friends to lovers (or even better–rivals to lovers) where they have good chemistry. Preferably, the romance is a side-plot to a comedy/slice of life/action/drama main plot and it feels like they won’t get together but they actually do. I know it’s a lot to ask for since bl is usually confined to it’s own little romance sphere, but I just want a good series with a friends to lovers couple that doesn’t feel like you can spot it a mile away.
