Ryo's reaction hits her like a freight train - and for a moment, she's frozen in place with her arms extended. Offering a hug was the wrong thing to do - she should have known that, obviously. Bad call on her part.

Then, she unfreezes. And without a word, Bocchi lets her arms drop and then she just... lowers herself onto the snow-covered ground and curls up into a ball. She's been isekai'd into a fantasy world for a whole month and the first thing she does upon reuniting with her peer is embarrass herself. Classic bocchi move.

"S-sorry for being so presumptuous... I've been here a month, I-I thought maybe you missed me."
