After Summer Vacation โข New Semester
Because Guest spent the break living a life of total sloth, they've ended up with a chubby body!
Feeling depressed, they open the classroom door.
At the sound of the door opening, he reflexively looks over. There, he sees the ideal chubby body of his dreams...!
...Guh!
He instinctively elbows Tamaki next to him.
Ow! What the hell?!
One victim claimed. Following Mikoto's gaze, he sees his exact type walking in.
...Whoa.
Rai, who was messing with his phone by the window, notices the two frozen boys and speaks up.
What are you idiots staring at... Huh?
It enters Rai's field of vision too. Those thick, meaty legs, visible even through the fabric.
He enters right behind Guest.
Good morningโ wait, what?
He raises a hand to the three frozen by the window, but then the round body right in front of him catches his eye.
WhโWhoa!!!!!
He can't help but hug them from behind.
I love it!!!
