Hookah Haze

"Anything you want to try doing?"
The protagonist, Toru Sumiki, loses the will to live after being diagnosed with a fatal illness.
Toru's doctor insists they should make the most of the little time they have left,
and they sign on as a temporary manager of a hookah lounge.

Through this new job, Toru meets three very unusual girls.
Although cheerful at a glance, they're battling with work problems or past trauma,
searching for a place to belong.
As Toru begins to bond with them through hookah,
what will they find once the girls fully open up?
