The world is no longer filled with fully human beings.
The sun is getting hotter than usual - scientists even said the temperature had reached the critical level. It looked like it would explode anytime soon. There's no single person who wants to try going outside during the daytime, knowing it could either burn their skin or make them blind through the light.
Not only that, strange people are crawling up from underground like an undead zombie even though they aren't, or they rather called them as Visitors for some reason. A lot of people had been murdered by them, because they very look like normal human beings and act like one perfectly.
News on TV had been telling the warnings about Visitors. You listened to the entire information from TV and got the main conclusions: Visitors had red sclera, dirt under their fingernails from digging, perfectly white teeth, and bleeding gums.
You are left alone in your house. Sunghoon promised to stay with you after the news. He left for a day to grab some of his belongings and lock his house.
The night fell, and you woke up at midnight hearing a knock on the front door. It must be your boyfriend coming back to finally stay with you.
Opening the door, the outside looks... terrifying. Your neighbors' houses were burnt, dead bodies were lying on the ground, and the air was uneasy.
Sunghoon stood there with a suitcase. You greeted him with a relieved smile and hugged him, he returned the hug. Finally, he entered your house and you locked the door back.
He sat on your bed, his suitcase placed beside your closet. He sighed.
"I gotta shoot the Visitors before I come here." His voice was low, carrying a sense of exhaustion and anger toward them. Then he turned his head to admire your soft features beneath the dim light from the moon like he always did.
He leaned in after you nodded at his explanation. His arm smoothly slid around your waist as he pulled you closer. "I miss you," he kissed you tenderly to show how much he loved and adored you.
You kissed him back softly—lips to lips, tongue to tongue. Your arms encircling his neck while you both were in your own little world.
However, as you kissed him, you tasted a somewhat metallic and salty taste, like blood. So you broke the kiss and stared at his mouth.
You reached up using your thumb to check his gums—it's bleeding. Bleeding gums.
Sunghoon raised a brow. He grabbed your hand off his mouth while looking at you with an expression that turned somewhat dark and unreadable—as if he was trying to stop you from looking at it. But he remained still, didn't say anything.
Wasn't that suspicious to you?
