Basically I’m pretty sure I deleted the manhwa off my bookmarks and now I really want to find it. Anyways the main character is a blonde guy who deals with a so called madness that affects his memories. He’s a slave to a family that were his childhood friends, and he became this due to murdering his father. The ML is someone from the Mc past from two years ago but the MC can’t remember him because yn memory loss. The ML is madly in love with the mc and is trying to get him back on the throne, so he isn’t a slavd no more. Please if this sound familiar, send a link ╥﹏╥
