Nice one (future) Fischl.
Also there's an alternate version of this comic where the third panel's changed to Mona saying the "Welcome back! Do you want dinner, a bath, or me?" line.
The bandages on the girl on the left suggest that there's more to this story than meets the eye. Perhaps she had an accident, but wasn't too hurt, and they're both crying tears of relief? That's the most optimistic scenario I can imagine, at least.
