[Youth Symbiosis: Use you as a mirror to become a better me]
When the straightforward and sunny Li Mingyu meets the sensitive and poetic Lin Yu, a complementary alliance between top students quietly takes shape. He taught her how to solve function graphs, and she took him to appreciate the world of poetry, promising to walk side by side to the top. Until the fierce old friend returns with the past and tears apart the trust with carefully woven lies - suspicion grows like a vine and the names on the report card fall off.
In the darkest moments, it is the best friend who is calm and insightful and the brother who speaks uprightly who clears the fog and illuminates the truth. When the scarred two people reunited in the countdown to the college entrance examination, what they formed was no longer a naive love agreement, but a growing alliance that stood against the odds. This relationship will eventually prove: true youthful love is when each other becomes the wind under each other's wings, flying to the promised starry sky in the process of tempering.
