Final answer:
Wang's "sickness" over Lotus typically suggests an obsession or infatuation which could cause strain in Wang's relationship with O-lan, potentially leading to jealousy, conflict, and loss of trust.
Step-by-step explanation:
It appears that there might be a mix-up in the provided references, which seem unrelated to the characters mentioned in the question. Nevertheless, generally speaking, when one character in a literary work is 'sick' over another, such as Wang's "sickness" over Lotus, it often leads to troubled dynamics in their other relationships, such as the one with O-lan. If Wang's "sickness" is understood as an obsession or infatuation with Lotus, it could deeply affect his relationship with O-lan by fostering jealousy, emotional distance, or betrayal. This can strain the marriage, create conflict, and may lead to the deterioration of trust and affection.
