After Turning from O to A, I Fell in Love with an Alpha [GB]

To reclaim the right to be first heir, which she lost after differentiating as an Omega, Elvira has no choice but to enter the Esper Academy and take part in operations to eliminate sources of contamination. But the detestable S-rank Alpha Shen Moyan outdoes her at every turn, repeatedly snatching the MVP title that would double her contribution points. When she finally loses patience and corners him against a wall to demand answers, her aloof, taciturn rival can't even meet her gaze at close range. His ears and neck are bright red... Does this guy like her!? After one mission, Elvira suddenly grows taller and stronger. She secretly takes a test: Your pheromones have mutated. You have undergone a second differentiation as an Alpha. Elvira's eyes widen in shock. She never dreamed something this absurd could happen. Thinking of the aloof beauty she'd finally managed to coax back, she decides to keep this secret well hidden. But just before her boyfriend is due to begin closed training, Elvira fights through her discomfort and lets him mark her so he can feel at ease. Who knew her pheromones would go berserk and expose her secret anyway? She tells her boyfriend after he comes to: "I've got one piece of good news and one piece of bad news. The bad news is, I've undergone a second differentiation as an Alpha. My physical abilities and mental strength are beyond SSS rank, putting me among fewer than ten people in the entire interstellar world. I'm as Alpha as an Alpha can be. The good news is, I've also received orders to attend closed training. I'll be on your team and in your dorm. Surprised?" A few things to note: 1. ABO setting, both leads are Alphas, 1v1, both sexually inexperienced, female top and male bottom. 2. Competitive, ambitious queen Alpha x a loyal Alpha who says one thing but means another. 3. The female lead is a bit of a jerk at first and nearly drives the male lead away several times. Read with caution if that's not your thing. Theme: True love can withstand the test of differentiation.
