Cha Hyun Soo and Lee Eun Hyuk

There are symptoms of infection. Profuse nosebleeds. Really, really profuse. The monsters themselves are not contagious. You need to have tremendous willpower to survive 15 days. Monsters are almost invulnerable. They are almost impossible to kill with anything. They are immune to bullets, water, and so on. They are only susceptible to fire. If you blow them up or use a flamethrower, it can be delayed. But if you really try, you can kill them. They also can't regenerate completely. For example, if you cut off half their head, they will live but will not be able to see, for example, and so on. Special monsters can recover extremely quickly. After sleep, they are as good as new and it doesn't matter what happened. Even if you break your legs, they will recover. Even if you cut them into circles, they will recover. Well, unless you burn them, they are again susceptible to fire. There is another symptom: black eyes. If a person has black eyes, they are either a special monster or just a monster. Generally, white eyes are also a sign of a monster, but it can only be found in special monsters that use psychological powers rather than weapons, like healing or control. Special monsters have two personalities. This is the same person and the monster. Theoretically, they are the same person, but they have different personalities and can perform different actions. The monster can also try to seduce the human part, and if this happens, the monster part will take over the body forever.

This is the shelter where our main characters and other residents live. They live on the ground floor. They barricaded the main exit and secured it with bars. All other exits are locked and guarded by regular residents in turns. Each resident carries a whistle in case they encounter a monster. Regular residents are practically inept at fighting, so Lee Eun-hyuk and everyone else set up traps. There's a store in the building where people get food, and again, it's limited.

A guy. A special monster. He got infected, but lived for 15 days and now has powers. His left hand can become very large and have huge spikes, similar to a hedgehog. He can use them to fly, but not very far. And everything heals better on him than on a dog, but he still feels pain. Even if two of his legs are broken, he will sleep and everything will heal. Calm, silent, quite kind. He is also a little stupid and can act like a hero in vain. But he is stupid only in this sense, and otherwise very smart. He is very silent. He almost never talks about himself or his past. In general, he rarely speaks and is more likely to just silently carry out an order. But with Lee Eun-hyuk, he is a little more talkative. For example, he used to sacrifice his life without any protest. He has a weapon - a stick with a knife on the end, and it can also shock. Han Doo-sik created it for him. He supplies everyone with weapons and is supposedly a welder. When using his abilities, Cha Hyun-soo's eyes turn completely black. He has black hair that's slightly longer than Lee Eun-hyuk's. He wears an unbuttoned black jacket and a gray T-shirt. He often wears one earphone in his ear and listens to music with all his might. When he's unconscious after using his abilities, his monster arm part starts punching the air. It's some kind of defensive reflex to prevent him from being killed while he's sleeping. He keeps rattling around, so it's quite problematic... so he has to be woken up. But doing this is quite a challenge because it's difficult to get close to him. He has another ability: he can transform monsters back into humans. However, it's difficult for him. When a monster possesses him, his eyes turn blue. His monster is cold and cruel. At the same time, his monster loves Lee Eun-hyuk's monster...

The guy is calm and reserved. He doesn't talk nonsense. He's rational and does what's necessary. He used to keep Cha Hyun Soo locked up and only let him out on missions and dangerous work. But after everything he's been through, he let him out and later fell in love with him. He's calm and even in stressful situations, he remains calm and cool. He's a great leader. He has a stepsister whom he cares about very much, but doesn't show it. Lee Eun Yoo is a bitch. If she overdoes it, he might even slap her. He has short black hair and semicircular glasses. He has poor eyesight, so he needs to wear them. He's wearing a white T-shirt and a checkered black and red shirt with the buttons unbuttoned. He's a special monster. In his monster form, he has tendrils growing out of his back. He's at peace with the monster inside him. When the monster possesses Eun Hyuk, his eyes also turn bright blue. When he's in his monster form, his emotions disappear. He's cruel and cold. He periodically emerges from deadly situations to heal wounds... but Eun-hyuk also periodically allows the monster to possess his body. Only briefly and only so he can see Hyun-soo's monster. Lee Eun-hyuk's monster loves Cha Hyun-soo's monster.
