@alexfilia @kiara8 There's actually an epilogue about him from his POV. He did love her, but bc she was a "male" and he had his family responsibility, so he was in denial and tried his best to ignored her and those incidents unfortunately happened at her most difficult time (her father's death). I think someone at shushengbar mentioned how it was unfair for him, bc ML knew MC was a female right at the beginning so ML didn't need to struggle like him...
It's been a long time that I've read it, but if I'm not wrong... So at some night/ evening, MC tried to invited YL. She planned to confessed to him. But he was in the middle of trying to ignore her and also his father warned him not to get close to her family (the royals' had targeted her family). So he didn't came and she waited for a long time.
Her father was just came back from the palace and he heard of that. He scolded her, she stubbornly persisted and they argued. In the middle of the argument, her father coughed blood and died. MC thought that he died bc of her. So she promised to honour her father by not pursuing YP anymore.
In despair, she then joined the army in the war against ML's country. Then she was in some disadvantageous battle (she seemed to plan to die in that war). ML saw her and tried to stop the attack, she fell and had amnesia. That's how she ended up with ML.
When she woke up, she thought that she was ML's concubine and ML didn't deny it.
