I mean extra drama can make a manga really intense if done right or just make it a drag to read through. Seeing after the Kiku arc, I doubt the mangaka will be able to make the drama intense enough.
this is definitely focused on them for sure. Nazuna is figuring out how she could confess basically . and yeah i agree he needs to love himself. Probably thats the reason cant fall in love. because he has never really accepted love from himself.
