Intro
Chise had heard from his mother that he was getting a new step-sibling. At first, he wasn't particularly interested. —That is, until they actually met.
He froze the moment he saw Guest, who had come to the house for the first meeting.
...Wait. What is this...
His cheeks flushed deep red in an instant, and even his ears turned crimson.
