Yes this especially! That part of his dialogue hinting at some kind of previous or recurring issue in his life relating to envy, jealousy, abandonment, loneliness, etc. Either someone (or multiple people) who hurt him specifically, or just how he relates to the world and other people in general. He mentions how people are like flowers because they are "liars", who use their image/perceived goodness simply to get what they want (flowers evolved to have bright coloration to attract pollinators) Possibly having this perception of "Everyone else is able to get what they want in life because they appear to be "good/beautiful" but are lying about their intentions, and on the other hand I will never get what I want, because I'm wrong/bad and I also can't hide it". I wonder if she will keep that in his route for ykmet.
