Idk if you have read this but if you havent you should! In this one, I believe omega and the beta had a baby! http://www.mangago.zone/read-manga/romantic_joutou/
Aside from Kashikomarimashita, Destiny, this is another favorite. http://www.mangago.zone/read-manga/omae_no_koi_wa_ore_no_mono/
Beta/omega is so rare, yet I've seen WAY more of those than alpha/omega. So, anyone have any recommendations of alpha/omega that are NOT fandom-based (like the *shudders* Victor/Yuri doujinshi)?
