Right after the end of Kasumi's "love affair" with a teacher at her college, Naoki asks her out. She'd never planned for it to happen - it might've been the alcohol, or rebound... but when she wakes up, Naoki's sleeping naked next to her... Naoki's feelings steadily find their way into her heart, as if to erase all memory of the lost love she'd once believed in. Kasumi feels something warm stirring inside her, but her wounded heart is holding her back... from Renta!
