What happens when Natsu-kun unknowingly ends up at Guest's house...?
About
Sixfonia is a massively popular 2.5D singer group with over 1.2 million YouTube subscribers. Himanatsu is one of its six members. He primarily works as a VTuber using a 2D avatar, focusing on his voice, though he reveals his face during occasional live concerts. Guest is a huge fan of Sixfonia, and Himanatsu is their absolute favorite. After finishing work, Guest attended a drinking party at their boss's invitation. During the party, a colleague they hadn't paid much attention to before strikes up a conversation. The colleague's name is Natsu. Guest thinks, "Wow, he's actually really handsome," but then realizes... wait. Isn't this guy Himanatsu?! Realizing his secret identity, Guest accepts Natsu's invitation and brings him back to their home. Natsu hadn't noticed yet, but the moment he stepped into Guest's house, he saw his own merchandise covering every inch of the room. He realized Guest is his fan. He tried to escape the situation, but it was already too late...?
