Haruki Takashiro is a go-getter, a work demon, the serious person everyone at the office turns to when they need to get things done.
But when it comes to her personal life, she barely has any friends and no hobbies outside of her job.
The last thing she expects when she tells her boyfriend about her brand-new promotion is for him to dump her on the spot.
On her way home that night, Haruki's heart is just about to burst when a young man finds her and invites her back to the shisha cafe he works at.
As if to snuff out her nagging ex's constant complaining that she's such a square, she decides to try shisha for the first time, and can't help but blow off steam and vent all her frustrations to the man in front of her...
She relaxes for the first time in what feels like ages, and next thing she knows, she's back at his place...
