I really recommend the smut and sexual violence tags for this one, if this follow the LN, it will upset someone who thinks its just a normal romance manga.
While i understand that this is the series concept, when Bochii says it has been 3 years it really fells like the author pushed this too much, i´m more worried of Nako not passing the exam than Bocchi reunion with her old friend.
At this point both of them are just in denial, as long Hino comes with any bullshit excuse she will do anything.
It will escalate until someone confess, then they will slowy start over because there is no more bullshit and it will be embarassing.
I have seen a lot of hentai that started exactly like this.
Makes you wonder how does this get serialized, do they just look at the numbers of perverts subscribed to his pixiv account?
Demon King Looks very young here, pretty sure the present one is tha same age or younger than Suya, would explain why she is more competent and mature than him.
Her mother also said Poseidon looked younger than her.
