I can’t remember the name of this manga… it was Japanese, I think in webtoon format. The MC was a freeloader/gambler and jumped from woman to woman. He got stabbed by a girl he dumped and reincarnated into an ABO universe. Right before he reunited with a gloomy guy from school and the both got isekai’d. The freeloader became an omega and the gloomy guy was an alpha.
