TEA NATSUNO

From YahmeeTeeh Scans: Daiki was a smart kid but on the day of their examination blood test to be performed and identify their gender, it turns out that he wasn't an Alpha but an Omega. Daiki was bullied as a child and became gloomy. In front of Daiki, he was weighed down by the gender gap and suddenly appears a High-Spec Alpha (Takizawa) who said he used to be Daiki's classmates. Daiki doesn't remember him at all and somehow he is wary of Takizawa's advancement of wanted to be paired of him. An Alpha united by obsession and a High-Spec, on the other hand an smart but grim Omega.

Ibuki Doi has never forgotten his first love from high school—Mikami Baba, the kind, handsome, and totally straight student council president. Though he was too shy to approach Mikami back then, Ibuki always held his idol near and dear to his heart, wishing him nothing but the best! However, when he learns Mikami is soon to be married to a man, he just can't help it—he's absolutely devastated. He drinks himself into a stupor to drown his sorrow but is surprised to wake up and find...he's back in high school?! Could this be Ibuki's second chance to make things go his way?
