A Voz (2019)

Korean drama is the original and Thai drama is a remake. The storyline and characters are very similar.

Both are remakes of the Korean original drama Voice. Both are following the original storyline closely.

It not just to be same but its a different than the other Thai dramas on channel 3. TRUE4U is cooperative to making the thai adapatation from ther other east asia.

Both male leads have lost the women they love to violence and are on a bit of a revenge kick. Seigi no Tenbin is milder in content than Voice, and it does have a tighter script.

Serial killers and more serial killers. Both dramas deal heavily with serial killers and the police attempting to catch them. The pacing is tighter in Aku no Hado, but Yuki Furukawa and Nattarat Nopparatayapon are equally proficient at playing super creepy dudes.
