Kashikomarimashita, Destiny
One of the best omegaverse stories I ever read. Though Aoi [Ω] is the eldest son of Toujou Family, but being an Omega boy - lowest rank of race, his dad even treated his stepmom over him. After his dad's gone, Aoi had to leave the house with his loyal butler Miyauchi [B]. The Saionji Family Head who owed Aoi's parents, took him in to work as apprentice butler. The heir Jirou [∝] & butler Kudou [∝] who're proud of their predominant Alpha & insulting Omegas, against it.

aaa This made me so emotional thanks to Ogeretsu Tanaka's magic. After Momo's baby with Kuroko is introduced to the couple Kise and Aomine, Kise begins to have insecurities about the future of his 8 year relationship with Aomine. Kise worries about their inability to raise children as a gay couple, which causes their relationship to break down.
Eigyou Nika!
Super cute, I feel like the manga really fleshed everything out and it was easy for me to start rooting for the both of them. Really nice art too. Sakisaka, a gay salesman, cannot make up his mind whether to treat his touchy-feely mentor at work, Toujou, as a love interest or a rival, and Toujou persists in sending him very sly and scheming mixed messages.
Yukidoke no Koi
Wish this author had more works, they have the ability to make stories fleshed out and realistic like I was crying soo much and I tend to read sad manga during the night lmao :'^) The energetic and pushy Sumito gets interested in his mellow high school teacher Someya, and falls in love with him. However, due to Someya's previous failed relationship he can't help but hesitate.
