I couldn't get off with my boyfriend... and yet my ex made me come countless times. Eimi has been with Haruki for six years now. But, he doesn't show any sign of wanting to marry, and their bedroom time on the weekends just feels like they're going through the motions. Haruki cancels their sixth anniversary dinner at the last minute, and just when Eimi is getting fed up with their relationship, she is reunited with her ex, Taketo Koga, who moves in next door! She loved Taketo very much, and he was her first... but not wanting him to think her a pain, she hid her feelings, and distanced herself... But, would things have been different if she'd been honest at the time...? Knowing her all the way to her deepest parts, his fingers are so hot, she could melt away...
