Bl with a girl in-between

Please recommend me something where one of them already has a girlfriend. And he genuinely loves/likes her, but begins liking the guy friend later. Slow burn would be appreciated, like the guy with the girlfriend noticing the guy love interest slowly and steadily. Can be manga/manhwa or novel, drama anything🙏 I’m actually watching Fragile right now (only on ep2 – came for the bl in yt shorts) and loving it.
