It is so very nice and sweet of you to respond to my comment! <3 And yes, you absolutely succeded to handle a delicate topic respectfully and with care (at least, in my opinion), and the characters' responses to the situation felt very realistic.
In this respect, there is something I'm curious about. I wondered if there was a deeper reason behind naming the characters as various plants/flowers, and googled their symbolical meaning. I'm not sure if I found some direct correlation (well, in the case of Strelitzia and Lycoris it kinda fits, but less so in the case of yellow oleander and lily?.. I guess?..), however, I noticed that all four plants have extremely beautiful flowers and all of them are to some extent poisonous. Which just cannot be a coincidence. :D And, as I see it, it fits the story perfectly, especially given how the main characters are capable of acting both constructively and destructively.
Still. I can't help but wonder, if the degree of their namesakes' toxicity matters. :P It was difficult to place lily on that scale, but concerning the other three plants, it looked kinda like "strelitzia < lycoris < yellow oleander", where strelitzia is only mildly dangerous and oleander is nearly lethal. At first I thought that it was kinda fitting, given that Strelitzia's course of (non-)actions seemed to be the most safe option (at least he won't cause any further harm "for the person's own good", making false assumptions about what would be good for the said person), buuuut then I thought that it unlikely was what creator(s) meant and intended to convey. Am I looking TOO deep? :D
(On an unrelated note, one of the other commenters said that their favourite character was Lycoris, and another commenter said that they found Oleander to be the most relatable. With me, you've got all three main characters covered, because my favourite (and one I find the most relatable) is Strelitzia. :'3 Although I like all of them really, really much).
Anyway, thank you again for your awesome work! I started to read Artificial Selection and I LOVE IT so far too. And I also keep Google around while reading it, because I feel I need it. :D
