Punch drunk love is a good one - the seme is toxic at first but he gets such a good character development
Starting with a lie is really slow burn too

"turning", it's one of the best novels I've ever read. The webtoon is releasing.
Slow burn BL without love triangle/no prominent 2nd male lead
Yaoi or shounen-ai, as long as it doesn't focus too much/waste too many chapters on smut. Preferably Korean webcomic, but long mangas (10+ chs), and manhuas without toxic semes Work too!
