Looking for a historical bl manhwa. I cant really remember the details but I remember crying so hard and thinking how good the plot was. It’s already completed. I think it was reincarnation? i only remember near the end where the mc died cuz he cut his throat with a sword in front of the ml. Btw ml is the emperor, he visits mc’s grave everyday… mc returned to his original body i think?
