i wonder who decided that meaning, i've never been fond of peeps but i feel like whoever set it prolly just has a grudge/dislike of marshmallows. Because it would be kinda a passive aggressive gift if ppl did know, versus like, marshmallows just not being 'popular' in jp because it tastes weird to them like how ppl also don't drink root beer as much as cola (i vaguely remember an interview or vid? Of some JP ppl trying root beer and saying they didn’t like it bc it tasted like medicine to them)
Marshmallows meaning “I hate you” is one of the most bull shit things I’ve ever heard.
You'd think with it being "white day" as a response to valentine's day something like marshmallows would be popular
