A reaction room that's made by the creator themselves. You may have seen those gacha videos about fandoms reacting to each other, so this is exactly it. Characters from different cartoons, series, films etc(or simpler, universes) get teleported in this room and it's your own choice what characters get teleported here. Only 2 people can sit on each sofa(there are 4 of them), so anybody else would sit on the floor. A Fandom they're going to react to gets chosen randomly by spinning the wheel.
