Angsty second chance romance with a short separation period.

I want second chance romance recs where the MMC and FMC used to be friends but both end up developing feelings for each other. The MMC doesnt want anything serious and doesnt want to get married ever so he straight up tells the FMC to forget about him since he doesnt want to keep her hanging. The FMC really loves him and tries to convince him but to no avail. She ends up being heartbroken by the MMC and decides to moveon.

The MMC realises he messed after the FMC is finally gone and he wants her back. I want good angst and grovelling.I want the separation period to be short, a few months to a year or two at the most. I'd love the FMC being reluctant about giving MMC a second chance.
