You, Beta, Pure-Hearted Tease [ABO]

After you transmigrate into an ABO society, you end up secretly dating an omega upperclassman in high school without really knowing what you're doing. Your families break you up, the school disciplines you, and you're publicly shamed because you "dated someone of the same primary sex." After that, things take an even more unexpected turn It turns out you aren't an omega. You were misidentified, and your true sex is beta. After that, you fall into deep confusion as you try to understand yourself and this society with six sexes. When the alpha female CEO who often comes to the bookstore with designs on you tells you to get in her car and pins you against the seatback, curious about female alphas, you don't refuse. When an elite beta man, who doesn't know he's your stepbrother, wants you to sign on as an intern at his company, he treats you harshly, then eventually asks to start an office romance and settle your marriage as soon as possible. You've heard this is the most proper kind of romance for a beta, so you don't refuse. When a mild-mannered alpha man who benefited from a switched-at-birth scheme wants to make it up to you, he lets your curiosity run wild and is willing to let you examine his body whenever and wherever you want. Eventually, the two of you develop an ambiguous relationship. Wanting to learn more about male alphas, you still don't refuse. How did things end up like this? You don't understand. You only know that after your upperclassman at the omega academy, the omega who actively pursued you, the omega who taught you to swing a racket from behind, and the omega who wanted to pretend to be an alpha and live with you, became your unforgettable first love, his family forced him to go abroad, and you fell into deep bewilderment. Until your upperclassman finally returns, grabs you firmly by the shoulders, and says, "Marry me. I want you. Only you." But you flatly reject his renewed pursuit. Because you've already figured out the differences between the six sexes. There's no need to date your upperclassman again. * She starts a new relationship after breaking up, but her final pairing is her first love * At first, the female lead is genuinely sweet and pure in love, but the cruel ABO society shatters her, and she becomes completely jaded * She's still a soft girl who falls over at the slightest push.
