Len has adopted hegemonic masculinity behaviors
Step-by-step explanation:
Lan has moved towards adapting herself to the set gender roles assigned to her by the masculine system and she is trying to fit in using the accepted rules for the females.
This is evident in her dressing sense as well as her voice which she is keeping at low and allows the men to dominate the conversation.
This stems from the fact that she is affirming the gender norms that have been perpetuated.
