Well most manhwa are having suck ending, this one is near suck, i mean when they will have to do an ending soon, the author still made hit and miss plot, like would have or not the 3some and author forgot it was junpyo flashback with dali only, so my theory they didnt plan for that drawing college girl to marry junpyo at first
And last but not least, junpyo mentioned about drawing his mom after all revenge cleared, the author forgot it again.
not good ending for me, if compared with another trash ending pornhwa probably this one still pretty decent.
