The premise of the story is that the MC and ML were married, and they just got divorced bc of misunderstandings (they both don’t think the other person loves them back). The ML passed away, and the MC went to his grave to pay him a visit. There he learned from the MLs friend that the ML actually really love him. Not sure what happened, but the MC was able to go back in time. Along the way he found out the the white moonlight of the ML was him all along. That’s the premise of the novel that I could remember. Does it sound familiar to anyone? Thank you!
