Doumeki and Watanuki need to invite Himawari over so that the three of them can play house together while they wait for Yuuko to return.
Also, Watanuki is totally going to die of food poisoning now. XD
(oh, Himawari, I do love you but you need to give your cookies to FWR, not Watanuki; you're trying to kill the wrong person!)
