A common troupe but fascinating watch

You know how you watch the typical cdrama and you forget later on cause most leave barely nothing to dwell on?
Well, it's different here!
The plot really was fascinating and I was always eager to see what would happen next. More importantly, the ML visuals was to-die-for!!!
Yes, I personally think they could have done much much better with the FL, but it was still okay.
Though same crappy time-travel into novel ending to be expected ?
