At chap 26, the misunderstandings are now cleared. MC and ML now know they love each other but but BUT MC still refuses to be with ML because she feels guilty of what she has done (hurting ML, Diane, tarnishing ML's reputation, etc.
So even though ML is begging her to stay by his side, grovelling, reassuring her his feelings, even giving her time to think...she's still like "NOOOO give me more time to think I'm such a sinful woman I don't deserve you boohoohoo" girl, you're just prolonging the agony, yours and his 😠
