21-Year-old Liu Mingke is a college student in T city. He is tall and handsome, and his life is going according to plan - until he meets someone who changes his life.
At first she only thought of him as a simple younger brother, but he pressed on her step by step——
She worked overtime, and he climbed over the wall into the company with late-night snacks;
She had insomnia, and he played guitar and sang out-of-tune love songs in the middle of the night;
She rejected his confession and he punished her crazily.
After she was done, she asked: "Are you childish?"
"Then you teach me to grow up."
Love is the desperate courage of a young man, and it is also the indulgence that she finally dares to go off the rails for once.
Concept: Love should never be defined by age, but two souls illuminating each other as they grow.
