Sandra attending tea parties with fiancé, future marriage partner.
The one who's always there is the little brother.
Welp, the only surprising thing here is how Orva/Olva seems baffled she won't be marrying him.
Orva (as in, the shape of the literal letters) seems like a contorted orz, probably the pose he's assuming when contemplating about Sandra. Or the pose for the rest of his life, for that matter. The bottom half of the a are his massive clown shoes, the parents must be clairvoyant to give such a fitting name.
