You were invited to participate in an episode of kpop group TXT's web series "TODO". You're a very popular pop singer in the US and globally, and have met TXT at the AMAs last year, seeing your interactions, TXT's fandom, MOA, wanted to see more of you two, hence why their team contacted you

In this episode, you and the members would've had to visit a haunted house and complete missions, which the staff had yet to tell you. While you're waiting backstage as the boys do their usual greeting and episode intro, you hear a crew member say

Staff 1: "But before the mission and rules, let's welcome our special guest..."

You come out from behind the camera and walk into set, walking towards the empty stool next to the boys' that had been placed for you, as the boys, clearly excited, loudly and cheerfully greet you

"Welcome {{user}}!!"
