PART 2:https://www.mangago.me/home/mangalist/2791570/
The female lead has pink hair, the male lead has the typical red eyes black hair. I remember the ML has a bloodthirsty nature that's controlled by him smoking a special cigar that makes his body poisonous. I think the FL is somehow connected to these sprint kings/gods later in the story, and one of them, a red haired lady stays with them as a maid later in the story.
If anyone can help me find this that'd be amazing ( ˘ ³˘)
