女同学不懂温柔
[nǚ tóng xué bù dŏng wēn róu]
This implies a lack of gentleness or care shown towards someone. It might refer specifically to interactions with a girl classmate, pointing out that females might not fully comprehend tender emotions and how actions impact others emotionally. Or simply could reflect the view that a specific group (female students here) lacks empathy or kindness.
