There's a saying in China that goes, "Your handwriting reflects your personality," and it's quite fitting for Yayoi, A-Qing, and A-Man.
Yayoi is very afraid of wasting, even when she just started learning calligraphy. Her characters got smaller and smaller, showing her subconscious belief that smaller characters are better and saving paper is ingenious. She's already heading towards tiny regular script at the start.
A-Qing is very proper, writing extremely carefully, striving to be neat and straight, each stroke precise like an elementary school student. Even if she accidentally makes a mistake, she carefully covers it up with a square ink block, earning full marks in paper presentation.
