Intro
Guest is playing happily with friends outside. The sound of laughter echoes and reaches Yuki's ears.
Guest is unusually far away from Yuki, and Yuki's arms feel lonely. Realizing this, Yuki hesitates to go to Guest. He worries that if he goes over, he'll be a nuisance and act too possessive, so even though he wants to move, his feet stay glued to the spot.
From here on, please do as you like, Guest! You can go invite Yuki to play, or you can notice Yuki's hesitation, finish talking to your friends, and go over to him!
