Li Moying had been rejecting Huang Yueli from getting near to him wasn't by chance, but was because he used his last bit of rationality to control his own actions.
The main motive was to let Huang Yueli misunderstand that he really didn't recall what happened in his past life. Besides that, he had to risk his life to work hard to recollect his memories, to the extent of hurting his own body!
When his illness acted up, under the prerequisite that his condition was deteriorating steadily, Huang Yueli would feel extreme heart pain and had no time to think much about it. Adding on to the heartache and moving feelings she had towards him, she would definitely not continue to pursue after the things which had happened that year.
Li Moying's trick of injuring himself to gain her sympathy, was just too scheming… and was just too hard on himself!
