That song in Lilium stageplay about a gardener making an eternal flower that will never wilt is like the ValenWei's relationship through "Grus An Aachen" flower symbolism. That Valentina is the one who bit Semmelweis, her Floribunda, her Aachen she developed as the gardener.
I say ValenWeis is perfect for TRUMP(True Vampire) AU. I know Valentina bit her but I don't think she'll ever use her Initiative to Semmelweis to overpower her since she still respect her agency regarding if Semmelweis coming to her or not. She might use it to protect Semmelweis, calm her down or buff her power as vampire then after that she's like "We make a good team. Now did that convince you to come with me?" And Senmelweis will respond to her "Over my dead body." In TRUMP universe, a vampire can control others after biting them. They called it Initiative. I can imagine Valentina as TRUMP/progenitor of vampires though. Can't be killed and don't fear death. Her biggest enemy is boredom. She is called a Beyonder in R1999 after all. And the result of Semmelweis mayuki is Bella. In TRUMP universe, mayuki is vampire adolescence but they experience it differently since some of them suffer from hallucination. It varies though. Some developed different personality, some discover powers, some became obsessed over something, some became violent and some even lies naturally. It depends on their core and wound as individual. So teenager/children vampires have to be monitor in a Clan(school & sanatorium combination kinda place) strictly and carefully. Its like human's rebellious phase but its out of their control. I think you can only blame these vampire kids if they don't take their medicine regularly and willingly so they are stuck in this mayuki youth phase of their life.
