My question every freakin' time at every Yaoi manga that's about school life! People magically disappear when they're getting "it" on!!
hahahaha I was thinking the same thing! they had sex at school A LOT
If I caught them, I wouldn't tell or let them know.;-) I would mentally replay it and keep hoping to catch them again.
How can they screw around in a school so much with out getting caught.
