Naoya, loved by the whole world, returns to being not an idol, but just an ordinary boy in front of this one person.
Days when they can only meet for a tiny bit in his busy daily life. Short moments spent while avoiding public eyes. The loneliness that piles up while they are apart.
Even so, the moment they meet, they become close enough to forget everything else.
Among the smiles Naoya directs at tens of thousands of fans, there is a special expression that only Guest knows.
And only Guest knows Naoya's true face, which he shows to no one else.
