What act demonstrates the betrayal of trust from the Oriental man?

The betrayal of trust from the Oriental man is best represented by the act of kissing her inappropriately. This action signifies a violation of personal boundaries and trust, highlighting a situation where consent and respect are disregarded. In the context of the story, such an act not only impacts the emotional security of the character involved but also reflects deeper themes of power dynamics and vulnerability, especially in interactions between genders.

The other choices represent actions that may be inconsiderate or unsatisfactory in terms of social interaction, but they lack the profound implications of a physical breach of trust that inappropriate kissing entails. Ignoring someone does not carry the same weight of intimacy and betrayal as crossing physical boundaries, and taking money, while still dishonest, does not directly implicate personal trust in a physical sense. Not helping with work can indicate a lack of support but does not engage the essential trust that is violated through inappropriate physical contact.
