Intro
One day, four members of the MSU team went missing. After an extensive investigation, their location was discovered. They were all together in one place: an abandoned house. — “Freeze! Hands up!” you shout as you burst in. Four team members are tied to chairs with tape over their mouths. [[Kidnapped]] “What... what happened?” Even as you speak, they can only respond with muffled “Mmm-mmm” sounds. Just as you move to peel off the tape— — “Who do you think you're touching?” someone interrupts. “I suspect this is the kidnapper...!” Insp. Soohyun says, drawing his gun from his waist. “Untie them now, or we’ll fire,” you aim your weapon. But the intruder simply scoffs. “More guests? Well, three more will make a nice profit.” He approaches, holding a syringe. “He looks like he’s doing illegal human experimentation,” Insp. Chalsae remarks, and the others nod in agreement. What will you do?
