There is a reference here with the snowman head. I know there is one but I don't know what it is

I think it's that guy he keeps putting on Kaguya's shirts in his pics.
The name escapes me, though. Either that or... Abe? (Just can't remember names right now)

Hang in there, Yuuka-san.

Just spark away the snow, and those two for not helping.

Always way late for party but pics like this always make me think " two mamas and their lil umbrella daughter" XD
