He had joined the military because of the princess.
With his skills, martial arts, and strategy, he quickly rose to the position of general.(Middle ke chapter hero ke military mein progress ke bare mein hi likha hua hai like fan changyu)
But then Wen Yu made it seem as if he had misunderstood her feelings all along, so that night he left without telling anyone.
(The hero thought she also had feelings for him because, back when the princess was disguised as a maid in his house, he had carved a wooden craft for her with her name/design on it before she left after revealing her real identity.
She always kept that craft with her. Even after returning to her position as a princess, she carefully stored it in a sachet and carried it around all the time.
Later, when it got lost and the hero found it, he realized that she truly did have feelings for him.
But, as usual, the heroine denied it anyway
Later, in the morning, a soldier came and informed everyone that he had resigned from the military.
Wen Yu acted completely normal in front of others, but after everyone left, she completely fell apart.
