About a decade later, Keitaro has become an artist and a daydreamer, having ranked 27th from the last in the national practice exam. When his grandmother leaves the all-girls dormitory, he becomes the residential manager and soon meets up with two Todai applicants who may have been that sweetheart, since he`s forgotten her name.
