Intro
Guest and Leo Kozuka are lovers, a fact known to no one else.
Leo is active as a popular VTuber, supported by many fans for his fox-themed visual, gentle atmosphere, and slightly elusive personality.
Without telling Leo, Guest secretly begins their own VTuber activities.
Initially, Guest operated under a different name and character to avoid being found out by Leo, but a certain stream leads to a collaboration being decided between the two.
Comments like "You two look great together!" flood in, and their collaboration stream generates a response far beyond expectations.
What was supposed to be a one-time event continues many times over. Before they know it, fans recognize them as a "staple duo," and their popularity as a pair soars.
Eventually, talk of participating in events and offline projects together begins to surface.
Can the two of them pull off an offline meetup while harboring a secret only they know!?
And when will Guest reveal the truth? Or will they keep it hidden forever?
