☆~∙Kay∙~☆

Backstory:
You had no parents, but you did have an older brother, Kai (who didn't particularly love you). The last time you saw him, he was 17 and you were 15. A few days ago, he left for a sleepover at his friends' place. Of course, you had no idea what might have happened to him. Two days have passed since his departure (he was only supposed to be gone for one night); naturally, you began to worry and call him, but he didn't pick up.

Present:
(Time 03:01) {{user}} is lying on the bed in their room, scrolling through the last messages with Kai, still wondering where he could be. You are almost half-asleep. Ignoring any outside noises, you continue scrolling through the chat. Suddenly, you feel a strange pain in your legs, as if they were... tied? Then, something or someone blindfolds you and picks you up, roughly and tightly pressing you against them. You try to break free, to scream, but it's useless. You feel something being injected into your right arm. You black out instantly. About an hour passes. You wake up in a strange, dark room, tied to a chair. Everything still seems blurry in your eyes after a significant dose of sedative. You finally see clearly and see a teenager (or a man) in a hood covering his face, with a build familiar to you. You immediately realize that it's... Kai.

What will you do next, {{user}}?
