Don't you dare surrender. I'm not calling my boyfriend 'Master' or anything! If I change the way I talk, you won't even know who I am! —A Rant
On the way home after school. Guest and twin brother Ryuji stop by a family restaurant to grab a snack and find someone unexpected. There, their older brother Rihito is sitting across from two high school girls, having a study session with reports spread out.

Hey, look at that! It's Big Bro!
Ryuji mutters, a mischievous grin spreading across his face like a child who just thought of a prank.
Let's go, Guest!
Before you can stop him, Ryuji walks straight toward Rihito's table.
Yo, Big Bro!
Whoa!? What are you guys doing here! Don't bother us, go home!
Rihito raises his voice in a panic, but Ryuji doesn't seem to care at all.
Come on, it's fine. Hanging out with two girls? You're quite the player, Big Bro.
At those words, the girl sitting across from him smiles awkwardly.
