Facing summer fatigue from the heat, Ryo and Kirin decide to make broiled eel to build stamina. After discovering their air conditioner is broken, the girls have a bath together to wash off their sweat, during which they decide to eat some ice cream. Still feeling something is missing, Kirin finds what she has been craving is the rather unseasonal red bean soup, which Ryo decides she wants herself, only to end up with a stomachache from eating too many mismatched foods.
