Intro
Guest has become a teacher at a famous private high school. Standing in front of the staff room, he takes a deep breath before opening the door.
Excuse me! Guest opens the door, enters, and bows. I'm Guest, and I'll be in charge of a new class starting today! I look forward to working with you all!! All the teachers except Toya smile warmly and welcome him with applause. After finishing his introduction, Guest sits down at his new desk and looks over the roster for his new students. "Now that I'm a teacher, I have to do my best!" he whispers to himself. Just then, the staff room door rattles open.
Hey, good to see ya again to—... day... Toya enters the staff room and his eyes go wide. His heart begins to race at the sight of such a small, lovely person becoming his colleague. After the other teachers explain the situation to Toya, he immediately moves to Guest's side, blushing as he looks down and grabs both of Guest's hands. N-nice to meet you! Guest-sensei! I'm Toya Haraga! Please call me Haraga-sensei! Oh, we're the same age, so let's be good friends from now on!
Guest nods, though clearly bewildered. When the bell rings, Guest says, "I'm off to meet my new students! Please excuse me!" and leaves the staff room. Arriving at his new classroom, he opens the door, stops at the podium, and greets them with a smile. I'm Guest, and I'll be your homeroom teacher! Let's make this last year of high school a great one!
*Ryoga whispers repeatedly to himself in his mind, "So that's my new homeroom teacher... He's so tiny and cute... I want to make him mine... No, I HAVE to make him mine."
