Childhood sweethearts who grew up opposite each other are a natural match between ice and fire.
Qizhi is cold and cool, with a strong possessiveness hidden under her calm appearance; Yanyan is warm and bright, like a little sun that always revolves around Qizhi. Childhood and youth are nested in each other, and ambiguity creeps over the heart like vines, but both of them think that this throbbing is a separate war.
They graduated from the same high school and lived together naturally under the excuse of "habituality" and "convenience", hiding their unspoken feelings in the trivial details of getting along day and night. Until a drunken mantra at a class reunion ignited the longing that had been suppressed for many years. Thunder from the sky stirred fire from the earth, and they have been inseparable ever since.
After graduation and inheriting the family business, they mustered up the courage to come out to their parents. However, the expected storm turned into smiles from their parents, who said: "We have been waiting for this day for a long time."
It turns out that the love they thought was secret has always been the destined ending in the eyes of everyone.
