Based solely on Shi Chun's shabby and casual attire, Second Miss Dong Liangyu concluded he wasn't someone who'd pretend to be cultured to approach them sisters.
Her observation and judgment on Shi Chun had no romantic inclination, but rather she noticed his poverty.
The reason being that Third Sister Dongliang Ying, who presided over the hall, had to manage as both shopkeeper and accountant while attending to miscellaneous tasks like setting up pens and paper, serving tea and water, was overwhelmed by her workload.
Oldest Sister Dong Liangyi handled the family's food and drink matters in the backyard and was busy all the time; she couldn't attend to the book pavilion affairs.
Old Fourth Dong Liangze had outside matters to attend to, so helping in the hall wasn't feasible for him.
