The villainess was poisoned to death... Huh? No, that's not right. I'm just sickly, you know?

"Katrina, I'm sorry, but I'm going to call off our engagement." A unilateral engagement cancellation announced by her fiancé. On top of that, the reason was blatantly infidelity—he had met his destined woman elsewhere. Her ex-fiancé spouting foolish justifications. His mistress saying selfish things to provoke her. The curious stares from those around them. Faced with such an unreasonable situation, Katrina's stomach aches in protest, and her frail body finally reaches its limit!? You were the ones who cornered me. Whatever happens next is on you! *Also posted on Alphapolis and Kakuyomu.
