"Asking him out in a cute way"?
Well, the very next page she does indeed go all Tsundere on him, which is certainly cute.
And her rather honestly honouring his request of no panties is also kind of adorable. She really does love him under all that Tsun, after all, and I'm glad he knows and acknowledges it.
I'm glad he appreciates her, and they seem like a cute couple. So since he can essentially ask her to wear anything on their dates...It makes me kind of want a series just showing different dates with different clothing.
