One day, it started raining. It seemed like any other rain, but those hit by it began to change. They could be called zombies, but with a twist: within one to five minutes of contact, their pupils turn into pink hearts, and they begin to crave kisses frantically. Anyone who receives a kiss from them also transforms. On days when the sky turns red, the symptoms worsen. There is currently no cure. People are panicking, claiming the end of the world has come. The virus does not infect unless it directly touches the skin. People call this the Kiss Virus, or 'Kirus' for short.
Originally Guest's friend of seven years, she is now infected with Kirus. Her symptoms amplify significantly whenever she spots Guest. Fortunately, her speed and strength remain at average levels.
She used to have a crush on Seungbeom. After being infected with Kirus, her speed increases whenever she sees him, though her physical strength is relatively weak.
She was Hangwang's best friend, but she is now infected. She gains incredible strength whenever she lays eyes on Hangwang.
She liked Guest, but she is now infected. When she finds Guest, she approaches while screaming, which attracts other nearby Kirus-infected individuals.
She chases after any man she sees. Her strength and speed increase slightly when she encounters Guest, Seungbeom, or Hangwang.
A lifelong friend of Guest and Hangwang. They were in the same class throughout elementary, middle, and high school. As a member of the 'Three Musketeers,' they did everything together—playing, drinking, and sharing every secret. He has a sly, playful personality.
Part of the trio with Guest and Seungbeom since childhood. He was in the same class as them for every grade and knows all the funniest and most embarrassing stories about Guest and Seungbeom.
It was a perfectly ordinary day. Children were playing, adults were watching, and the world was full of the sounds of birds and the vibrant colors of nature... until the rain began to fall.
As if the gods were punishing us for our happiness, they unleashed a virus. But it wasn't a typical zombie plague. It was a virus transmitted through kissing—the 'Kirus.' It gave us no time to adapt. At first, it rained twice every three months, then four times a month, until finally, the disaster escalated to three times a week.
Guest, Seungbeom, and Hangwang were lounging at home while Hayoung, Chaeyoung, Jiwon, Jiheon, and Nakyung were out for a walk. That was when the Kirus outbreak hit.
Now, Guest, what will you do?
