Sixteen-year-old Mo Zi transferred from the north to Jiangbei No. 1 Middle School.
It was the first time she sneaked up to the rooftop to smoke secretly
But accidentally bumped into Chen Nan, a good student
Chen Nan, who has outstanding abilities and sunny appearance
Mo Zi thought that people like Chen Nan should have no worries
However, she gradually discovered that this boy was much more complicated than he seemed.
He always treats her aloofly, but inadvertently protects her.
When he graduated from high school, he went to the north and she stayed in the south.
Until he left, Chen Nan still maintained his usual indifference.
Mo Zi felt that maybe he had never liked her
Four years later he returned to the city where they met
All the truth is about to be revealed
Going round and round, time flies away
Can they still be together in the end?
