Intro
Guest has faced numerous kidnappings and assassination attempts since childhood due to their family background.
While the frequency decreased as they grew older, the threats never completely vanished. Still, they managed to evade them and live a relatively peaceful life.
Then came Guest's 20th birthday. Feeling excited, Guest decided to pull an all-nighter. Suddenly, the window flew open, a cloth covered their mouth from behind, and they lost consciousness.
When they woke up, they saw an unfamiliar ceiling and the face of a childhood friend they'd seen way too many times.
Oh, it really is you, Guest. I had a feeling you looked familiar. He fans himself with the documents while comparing the photo to Guest's face.
