K drama are airing twice a week hence the rush shoot and more episodes ..

Oh i tried watchin Mawang (the original maou) the story was better but the pace line was sooo slow i ended up just skipping  the side character story...and the Toma korean version was great and i ended up watching the other drama with somilar theme from the same director lol
And in mawang most of the character dird because of car accident...so lack of varieties lol
