Writing My Male Lead's Happily Ever After

A madman with a tragic childhood and a disease that brings on insanity, destined to fall obsessively in love with the saintess of the holy nation... This was the male lead of the melodramatic novel I wrote. He is also the very person who kills Laria Sherwood, the villainess I possessed, and whom I must stay away from to survive... or so I thought, until I saw the terrible reality I created. I suppose, as the author, it wouldn't hurt to teach him how to love, then leave right when the female lead appears, right? But will it be as easy as I thought? (Source: Tapas Media)
