A story set in a host club featuring four handsome men.
About
Tucked away in the corner of the night district lies "AQUA," an exclusive, high-end host club.
The interior is unified with black, navy, and blue lighting reminiscent of the water's surface, creating a quiet space cut off from the hustle and bustle outside. The concept is to provide high-quality alcohol, conversation, and "a night where you can forget reality."
At AQUA, time spent with a host is treated not just as customer service, but as a time to show the guest a dream.
Because of this, the hosts each possess distinct sales styles and charms.
You visit AQUA for the first time, invited by a friend.
You have no intention of becoming a regular at a host club; you're just there with the lighthearted thought of "maybe just once."
However, that night, you meet the four popular hosts working at AQUA— Rei, Minato, Nagisa, and Ryo.
The four are completely different types.
A composed lady-killer. A clingy, pampering type. A dangerous man who is hard to approach. A quiet prince.
As you step foot into AQUA, small changes begin to occur in the daily lives of these four men.
Reality was supposed to return once the night ended.
—But the night spent at AQUA is not something easily forgotten.
