it could be a foreshadow that he might get posion later.
Foreshadowing is when something is mentioned, but foreshadowing wouldn’t be 4 chapters long and still going. I could be wrong who knows!
well, if it mentioned then there is a high chance of it being foreshadowing. I don't know if there is a rule on how long foreshadowing supposed to be. I kinda skimmed through the chapters, so I don't know how many times poison has been mentioned. But yeah, it could totally be an irrelevant event added to the webtoon to show what kind of treatment/training Ain has to go through.
The first chapters were amazing, but lately I’ve been kinda getting annoyed by her... like we get it, you think he is cute but I want her to find out who he really is and I feel like this plot is making ‘poison’ into a major thing when it really shouldn’t be....but other than that I would like to also see more of the dad
