You didn't even add that he *does* later apologise to her sincerely, and actually even regretted treating her as he did IMMEDIATELY the morning after. Doesn't make it right, but it's a lot better handled than many other comics out there. Not to mention if you consider the fact that he has just been told he'd been humiliated by being sent the wrong bride, and has also just returned from war. Again: he is not unguilty of the crime, but he does apologise and treats her sincerely afterwards.

Did you forget she is a former prince in hiding? Also, you complain about girlbossing yet also complain when she shows signs of weakness. I will admit that she could've shown better strength and independence but also consider she has lost her only support: her mother the queen, and is stripped away from her male persona entirely. Her only motivation was to live to see the next king die as instructed by her mother. She was a living ghost until she met the ML, proven when she later explicitly said "I am alive again because of you" or sth to that effect. Plus, the country was in ruins, not sure what you expect a runaway-prince-turned-commoner-girl to be able to do and continue to "girlboss" since she also mentioned having nightmares of hearing the people who sacrificed their lives for her to escape.

+1 FL, a child, learns to step up to the cruel king to save another innocent child despite being terrified. +2 and how to forgive herself of the deaths that were caused for her to escape from the palace during the siege, eventhough it isn't exactly her fault. +3 She later learns that she is worthy of love (and thus to love and even have a family with the ML). Their sacrifices were orchestrated by her mother to ensure her child's safety.

+4 She also later promises to return to her son after the final war in the story, and she swore not to be like her mother who was unable to return. +5 overall at the end she was able to protect her people, which she was unable to do while she was the prince and when she was forced into disguising as a commoner.

where the ML forced MC to be with him the first time they met, regardless of the fact that they are going to be wedded the next day.

Yes, that's where ML rap*d her when they met for the first time.

yes their first time was a dub-con, ML had his reasons and you can say that it was a realistic action if you think the times the story is set (medieval Europe) and that FL was impersonating a noble lady and the wife of ML and the ML was a Duke who learned that they send him a maid as wife, So ML when he learned about this lie / insult (he was a duke and they send him a maid in secret as his wife....)

he chose not to wait for the wedding night and slept with FL sooner, FL was there to marry him and sleep with him just not that night (FL wanted to do it in their wedding night)

But he also regretted it and spoke about it with FL later and apologized.

ps. im not saying that what he did was right (because it wasn't) but I can see his reasons and the times/era that FL and ML where living.
