Idol wo Sagase

Chikako Fujitani (18), 1st year at the Hanano Women's College starts living alone at the same apartment as Kanro (an aspiring mangaka from the same school) and Chiaki (a bus guide who pretends to be a college student to get a man). While on the "Country-Bumpkin" tour he meets Iwata, reconnects with her middle school crush, Nagae, and meets the landlady's son, Makoto. It's the kind of story about the bold and flimsy feelings of college students on an awkward, realistic love.
