Gentle little fairy & tough-tongued handsome guy
Xu Zhiyou&Jiang Cheng
Xu Zhiyou grew up with Jiang Cheng. The two had a very good relationship and went to the same elementary school, junior high school, high school, and university together.
I thought they would be lifelong good friends, but after going to college, Jiang Cheng became confused when he saw a suitor around Xu Zhiyou.
So, from being lifelong good friends to being lifelong lovers.
"The relationship hasn't changed, it just changed its name."
