After Reincarnating as a Female Alpha!

Song Ling never expected to wake up in an ABO world as a female Alpha. The original owner was also... a scumbag Alpha. The original owner forcibly gave a temporary mark to the man her parents had arranged for her to marry, then humiliated him, saying he was an Omega who wasn't cute or affectionate, acted just like a Beta, spent all his time working, and was dull and old-fashioned. She even declared that she would definitely break off the engagement. ...Don't ask how she knows all this. Because when Song Ling transmigrated, she was right there in the middle of the marking. The other person used the last of his strength to grab her as if she were a lifeline. On top of that, the original owner had secretly been keeping a young male Omega on the side, behind her parents' backs. Now Song Ling is at the engagement-breaking meeting, with both sets of parents glaring furiously at her. The male Omega who was forcibly marked sits across from her in a formal, elegant suit, seemingly dressed for the occasion. Hearing her announce that she wants to break off the engagement, he sits bolt upright, hands clenched on his knees, his face slightly pale. A faint trace of pheromones hangs in the air, giving away what happened between the two of them last night. Even if it was only a temporary mark. And even if the original owner injected her pheromones into the back of his neck with a syringe. Outsiders won't see it that way, though. Song Ling's fingers tremble: This is intense. I'm helpless. I want to jump into the river. Reader's guide: 1. Female Alpha, male Omega. 2. A mountain of personal worldbuilding. Theme: People should reflect on themselves and strive to improve.
