would be the first to have a kid. Though he's the one with the longest standing relationship since him and Amaryllis are childhood friends. When it comes to the future kids the order of oldest to youngest would be
Tsubomi
Solanum's daughter
Xanti's child
Hanasaki

and Iris if she has one is TBD

I actually already have a name planned for her too, as well as his most likely girlfriend. As for Xanti there's also a high chance he'd have a kid too, funny enough his probable girlfriend has a close connection to Solanum's lol. What I find funniest though is Lila whose the 2nd youngest of the 5-

When it comes to the eldest sister Iris it's still TBD as I'm unsure (I don't have a personal ship for her yet) When it comes the youngest sister Orchid it's probably a no unless she adopted then maybe. As for the older brothers though Solanum almost certainly would have a daughter-

Hanasaki would be about 3 years younger then Tsubomi and would be the more shy reserved daughter compared to Tsubomi whose more outgoing and sociable (they mirror aspects of their parents)
All that said it got me thinking about if Lila's other siblings would have kids too and well-
