I'm assuming this won't have a coherent plot so much as it'll just tick trope boxes until the author runs out of ideas and is forced to commit to some sort of ending.
But I think it would be funny to see Kubo end up a successful mangaka, but also alone after alienating everyone around him with his behavior and antics in the process.
Also, it's not like he can change, because the moment he does, our Main Heroine here will no longer find anything attractive in him, but him not changing also means he'd never see her as someone he could actually date and have a relationship with (even outside the parameters of this mission of his).
So I'm kind of at a loss as to where this will ultimately go. As it stands, they're kind of diametrically opposed, and given his entire focus is experiences and not genuine romantic relationships, I sorta feels like this will be more meta-commentary than straight-shooting romcom. The pieces are all there, but the characters feel a bit too meta-savvy and archetypal to faithfully fill the roles they're meant to play (especially when events jump around as quickly as they did this chapter).
I guess as a deconstruction of the silliness of the genre, though, it's entertaining enough, if you treat Kubo as an insane third wall-breaking entity and not a character in the world worth taking seriously.
Thanks for the TL.
