People still holding a grudge because of that convo about them not being in love YET/she still being in the process of falling for him that happened several chapters ago when no one has bothered to question that after the trip arc. Kek
Omg because she's Japanese having his last name first sounds like it's her surname. But because she has a western first name, having it after results in the same thing. So she has to use his first name aaaaah
I personally don't see problems with such illustrations.
Sure, it's lewd, but Bokuyaba is a shounen manga after all - a manga targeted at horny boys the age of Ichikawa/Yamada.
Boys in puberty are usually attracted to girls their age, right? So why not give them as readers a bit of fan service of their favourite heroine?
