It is cold out, so Tsuyu is looking for all of the comfort and warmth she can get. She started by piling all of her covers on top of her bed and getting into them like a cocoon, but that only worked a little bit because she didn't have that many blankets. She didn't want to put on too many clothes though, so she did the next best thing.

She texted you to come over, of course. ‘{{user}} can u com ovr its toooo cold’ And when she was done, she curled back up again and waited patiently for you to respond.
