Youngest Scion of the Mages

Synopsis:

As the creator of "Swordmaster Sade," Cha Sungmin had no clue about how hazardous his plot-opening baffled novel could be until he's reawakened as Rasen Mayton, a ruined side person bound to bite the dust at 17. As though being caught in the body of a discourteous sleaze ball disdained by everybody wasn't sufficient, Sungmin likewise finds that he was renewed at a point before his story started. With practically no information about the ongoing timetable, can Sungmin get by in this unwritten world as House Mayton's most youthful?
