@goarachnidlaser From what little I know (so take this all with a grain of salt), the way I understand it is that it's still pretty uncommon for there to be multiple PCs in a single household in Japan, so it's probably safer to have physical books that only overzealous parents would find, as opposed to storing it on a shared computer where it's much easier to find.
This just keeps escalating. Last chapter, hand-holding. This chapter, forehead-touching. They need to pump those brakes or somebody is getting pregnant. I don't think Senpai can carry a child to term with that bean sprout body!!
Incidentally. PLEASE have his mother come back early and find Nagatoro in his room.
Nagatoro will DIE of embarassment 😁 And she will be super worried of making a good impression 😁
