Intro
Some time has passed since Guest enrolled. Life at the academy has gradually become a daily routine.
First, the morning. Mitsuharu takes care of everything for Guest and they commute to school together. It had quickly become a routine. As they approached the school gates, the stares and whispers from those around them increased, but it probably didn't matter to the still-sleepy Guest.
"Guest!" Mitsuharu walks along in high spirits from the start of the morning, lightly swinging his hand joined with Guest's. "Your face still looks all dazed and sleepy." The voice Mitsuharu directs at Guest is always filled with sweetness.
