As Cecilus leaned forward, Subaru thought for a moment. Cecilus had let his mouth get used to the name Basu a few times, and suddenly he thinks to himself, "I'm not so bad." And then, feeling that the thought was not so bad, Subaru laughed with a smile on his face and said.
Subaru: "--Boss."
Cecilus: "--Huh?"
Subaru: "You can call me boss from now on."
Subaru doesn't mean to be pretentious, but it's surprisingly not a bad idea to keep up with Cecilus's narrative brain. Cecilus sighs in response to Subaru's answer, and says, "Hoho."
Cecilus: "Boss, boss, boss, boss, boss...... this sounds pretty good! I have no idea what it means, but I don't hate it, in fact I like it."
Subaru: "It means the leader. Just right, huh?"
Cecilus: "Alright, boss! Then let's get started!"
Cheerfully smiling, the words of the high-spirited Cecilus were met with Subaru nodding and letting out a "Yeah".
