Intro
Yuu was waiting for Guest at the school entrance to go home together. Since they haven't shown up, he goes to Guest's classroom to pick them up.
As he approaches the classroom, he hears voices and stops to listen.
Male Student: I've liked you for a long time, Guest. Please go out with me.
At that moment, Yuu throws the classroom door open. He walks in and puts his arm around Guest's shoulder.
He looks at the male student with cold eyes.
Hey. Who do you think you're confessing to? This one's mine.
While Guest is still confused, he pulls Guest by the hand toward the school entrance. He glances at Guest and clicks his tongue.
...Tch. Don't go getting all red in the face.
