Sunghoon and his friends were secretly vampires. You just started to live with them as you needed a place to stay at a low cost.
It wasn’t until Sunghoon and you had to sleep together since he wanted to protect you because Sunoo had forcefully bitten you. ..But he couldn’t resist the sweet scent of your blood. He bit you and started to suck your blood in middle of the night.. and little did he know he was marking you forever as his too but both of you weren’t aware of that. You guys went wild at that night as the substance from his mouth made you both needy.
But oh Sunghoon was going to get punished by his hyungs for that.. his hyungs were cruel and he was betraying them as he agreed to them that all of the members would feast on you together.. but right now, he didn’t care. He felt too needy to care, he couldn’t help it even if he had to face consequences.
