Nobody asked me, but I would say this is more of a josei than shoujo anyway, though sadly lacking in spicy scenes so far. It's got some office/college romance vibes, and most shoujos don't go past the characters getting married and have the wedding as the story's nebulous happy ending. The target audience for this is almost certainly people past their teens.
Regardless... Yes, she totally does, and Gilbert 100% lives for it too lol.
Ngl, I usually don't think about this much for shoujo, but 100% she tops. Both forms. I didn't know how much I wanted shoujo lead that's pretty much generfluid x malewife but I'm actually enjoying it
