Lin You and Lu Xingchen are childhood sweethearts who have known each other since they wore crotchless pants. They are also famous e-sports legends on the university campus. She is the sharpest ace assistant beside him, controlling the battlefield vision with one hand; he is the sharpest assassin's mirror behind her, taking the enemy's head in the midst of thousands of troops. Their "mirror battlefield" tactics are invincible and carry a common professional dream. However, a sudden misunderstanding caused this perfect pair to part ways and their dream came to an abrupt end.
Many years later, an accident forced Lin You, who had become a game artist, to start an awkward "cohabitation" life with Lu Xingchen, who was already a cutting-edge architectural designer. The former tacit partners have become the number one enemies fighting each other for bathrooms, study rooms, and games every day. He is sharp-tongued and critical, but she tries to show off his every move. Under the seemingly tit-for-tat daily routine, there are hidden unsolved knots and unspoken concerns from back then.
When the gentle and handsome director of "Tianxiang" pursues Lin You, he becomes jealous and confused.
That night, with red eyes, he said to her, "They say that a bamboo horse is not as good as falling from the sky. Are you going to leave me and pursue the falling from the sky?"
But she said, "Who said that a bamboo horse is not as good as falling from the sky? At least with me, you will always be my... Only one."
Trust was rekindled in an instant, and the tacit understanding spanned the gap of time. All the quarrels, awkwardness, and duplicity found the answer at this moment: they thought they were in a contest that related to victory or defeat, but they didn't know that in the years of companionship and contest, they had become the most inseparable part of each other's lives.
"Others say that falling from the sky is a destined romance, but I want to prove that childhood sweethearts are the longest love letters written by time to love."
Purpose: "Others say that heaven is a destined romance, but I want to prove that childhood sweethearts are the longest love letters that time writes to love.
