Ever since he was with Qin Han that one time, he actually had not touched another woman. Even when he was with Mu Jinxi, he did not touch her. They slept together, but he merely held her, without a single thought of wanting to touch her.
It wasn't that she wasn't pretty enough, it's just that he had a personal quirk — having touched one woman, he had no desire to touch another. But the only woman in his heart was Qin Yin. That's why he was so torn back then. To clear his thoughts, he left Jiang City, he left the country.
He stayed abroad for two years, during which he thought he understood, thought he could let go of his past.
However, the very first night upon his return, he was plunged back into that mess. He figured that he needed to settle everything before starting anew.
But then he saw Qin Yin again. He realized that all the effort he put in over the past two years was in vain. He simply couldn't forget Qin Yin. Therefore, he told Nan Fu he returned for Qin Yin.
