Usually the author pays an artist for a promo just to materialise their story and perhaps get sponsored/ contracted by (korean) manhwa/webtoon studio, usually the promo artist doesn’t follow up with drawing the manhwa, they just do promo. Various artists mean different styles of manhwa and probably this was the only artist available to draw it so the style changed a lot. Unfortunately, readers were interested more in the art style rather than the story

Is it just me or The promo's art style and the art style used in the official are way too different? I would've thought that it's gonna be the same or similar atleast, I really liked the art style in the promo... what happened? ╥﹏╥
