In exchange for keeping it a secret, he makes an unexpectedly serious proposal. He wants Sumire to model the lingerie he designs so he can get feedback and test the texture and functionality of the product in real situations. Puzzled as she has imagined much worse, but mixed with such shame and confusion, she spontaneously asks him to "Have sex with me"!!!
