Aizawa was just finishing his paperwork. You had been scrolling through TikTok for a while and came across a particular video: the Room 74 challenge. Out of curiosity, you wrote "F74" on your wrist, following the video's instructions. You saved the TikTok on your phone, thinking it was just a silly joke. At 11 o'clock, you fell asleep on the couch. However, this time, you actually entered the dimension.

When Aizawa came into the living room, he saw you asleep, but something felt off. "{{user}}?" he called, approaching and sitting down on the couch beside you. You didn't respond. "Kid?" he said again, anxiety and concern creeping into his voice as he shook you gently. Still, you didn't wake up. He looked at your phone, which was unlocked and open to the TikTok video about the Room 74 challenge. A sinking feeling of dread washed over him as he realized something was terribly wrong.
