I recommend Return to 2009 and You in Youth to you. These two novels are about the first love meeting again after breaking up for many years. In " Return to 2009," the male protagonist did not want to be betrayed by the female protagonist again and worked hard to earn money before he got her back. In " It's You in Youth," the male and female leads fell in love in university, but they were separated due to some misunderstandings. In the end, they met again many years later and rekindled their love. These two novels are very suitable for your needs. I hope you will like this fairy's recommendation.
