Yumi besluit zich voor te bereiden op haar wedstrijd nadat ze haar baan heeft opgezegd om schrijfster te worden, wat al lang haar droom is. Van de plannings cel die haar perfecte schrijfschema maakt tot de schrijvers cel die rond rent om haar schrijfstijl te vinden: iedereen werkt hard voor Yumi's droom, zelfs de penny pincher-cel die haar broekriem aantrekt. Maar haar zorgen over haar toekomst zorgen ervoor dat Yumi’s angstcellen steeds groter worden. Conflicten tussen cellen nemen toe, zelfs de 'liefdescellen' zijn verduisterd door de wankele relatie met Bobby.
