I like stories where people bicker or poke fun at each other.
This had quite a share of that so it was fun.
That said, Hanamori's reasons for things were interesting to see. Her point of view parts helped me a lot to understand her actions, which at the start of the novel felt a bit weird to me without that background information.
I enjoyed the parts after the main story too, they were severely lacking in dates and chilling at home moments without that
Not like it's an actual issue, but i quite like scenes like that, specially after the main points get solved.
