https://www.mangago.zone/read-manga/norainu_no_yoru/ (the alpha uke x beta seme manga)
https://www.mangago.zone/read-manga/like_a_tidal_wave_from_pheromone_shower/ (alpha x omega, they're a switch couple)
https://www.mangago.zone/read-manga/omega_bite/ (omega x omega, the plot twist is shitty which I'm pretty sure is y it has such a low rating)
Hopefully u like them and haven't already read them lol
