Not that it matters but my opinion on Marcelle feelings on both the Toudin siblings.

I don't want to trend on anyone's head cannons, but to me. Marcelle values her friendship with Falin way more then her relationship with Liaos, although he is her first major crush. She will only have one college friend in her life Falin, but likely many loves in her life living so long. So she loves Falin more then Liaos but is romantically attracted to Liaos then Falin. just my thoughts please dont hate me.
