Love doesn't depend on gender or strength.
Tall, handsome, domineering underclasswoman vs. gentle, virtuous, married senior
The first time Xia Qing (male) met Song Zhiluo (female), he didn't realize she was a girl. How could such a dashing, handsome guy possibly be a girl?
Once they got together, well, what need was there for him to assert his authority as a husband? That was Song Zhiluo's job. He just had to mind his duties as a husband.
A sweet, short campus romance with no melodrama, just a simple love story.
Leans toward a female-top, male-bottom dynamic.
