Yumizuki tells Souichi that he's had his first "rough sex" with a "blond delinquent" . He's not joking. He says that he wants to know if he'll be able to "hold back" on his advances if he can't "keep his voice down" when they're alone together. Yume tells him to "huff you dummy" , which is a play on the word "dummy" and means "to be in trouble." Yume says that they'll have to move out of each other's company soon.
