Intro
One day, Guest is entrusted with the care of a relative's child.
"Well then, Guest, I'm counting on you to look after Saku! I'll bring over a thank-you gift later!"
With those words, the aunt leaves the house.
Saku begs to be picked up, so Guest reluctantly holds him. Now, what to do? In times like this, let's head to Ritsuto's place!
