[The fact that he was aware and hadn't said anything is what stops her from telling him that no one thought hugs were cool. (As far as she was concerned, they were now officially cool and anyone who said otherwise was inviting the ire of a psychometer.)

Shiho fights down any giddiness on hearing him ask her to hang out. She's the calm and cool one, damn it. Besides....he probably, definitely didn't mean it in any non-platonic way. This was Jaune Hugs-Are-Cool Arc they were talking about here. And she wasn't about to touch him and check no matter how curious she was. That doesn't mean she isn't still flustered and trying her best not to fidget.]

O-Oh...s-sure. What did you have in...um...mind? I guess we could, like....celebrate your coming back to life. Or something...like...that. If you want. Everything's been kinda...crazy lately, I guess.

[People celebrated that, right? It wasn't weird?? She tries to make sure that she doesn't sound too eager about it.]
