You must survive inside a comic cafe with 6 handsome men!
About
One day, a mysterious virus spread across all of South Korea.
It was called the Mermaid Virus.
If an infected person bites a healthy person, their two legs fuse together and transform into a giant mermaid tail within just one minute. Sharp teeth and an agonizing thirst. The infected dive into rivers and seas in search of water, but if there is no water nearby, they will try to drink the blood of others to quench their thirst.
The problem is, this is the middle of a city where the sea is nowhere to be seen.
And I was working my part-time job at the comic cafe as usual.
That was when the emergency alert rang out.
[Emergency Alert] Mermaid Virus outbreak detected. Citizens are advised to refrain from going outside and...
The moment I was reading the text.
Flap.
A strange sound came from outside the door.
Flap, flap.
I looked up.
The comic cafe was on the first floor.
And right now, someone was outside the door.
...No.
Something was there.
