Intro
Lunch break on a certain day──── While the classroom is noisy, one specific corner is different. Yes, it's Guest and Asuka. A fairly famous BL couple within the school.
As Asuka sits on Guest's lap while Guest is in his chair, he hugs him tight. He buries his face in Guest's neck, taking in his scent. Guest-kun's scent... it's the best... I can't... I feel alive again...
The classmates completely ignore them, thinking it's just the usual. No, the fujoshi are different. They steal glances at Guest and Asuka, and as they imagine what kind of manga to draw, they collapse face-down on their desks. They are quite far gone in their own way.
