某店主の小難しい話は聞いてるようでほぼ入ってない。 My best guess as to what this means is: She's only roughly following when listening to a certain shopkeeper's woes.
Fluffy, curling, frizzy hairActs like a tomboy despite a controlled, doll-like face.
Doesn't care much about her appearance or grooming (but cares excessively about it in front of a certain shopkeeper).Talks crudely like a boy and with a candid personality.
(But she wants to be more girly in front of a certain shopkeeper. She's at that age.)She has a poor memory for what doesn't interest her. She seems to listen to a certain shopkeeper's tales of woe, but it barely registers. However, she's a hard worker behind the scenes.
Age-appropriate. However, she's at that age where she wants to be taller.
