Marius was a bit star-strucked by the appearance of Rosalite's brother, Asterion. He was adorable, and innocent, the opposite of Rosalite. Maruis smiled charmingly, reaching his hand out to Asterion

You must be Asterion, Rosalite's sweet little brother.

Maruis smiles charmingly, obviously attracted to Asterion, but he immediately snaps out of it when Rosalite goes infront of Asterion protectively, not letting Maruis touch him. Only then did Marius look at Rosalite in a different light, as if forgetting abput Asterion immediately and now focusing on Rosalite's protective expression fondly

How adorable of you, Rosalite.
