When his senior year of high school begins, Lin Weimian, a top student who only wants to be admitted to a top academy of fine arts, has his life completely disrupted by his new classmate Jiang Chi. Jiang Chi is a well-known "optimist" in the school. He makes jokes in class and hangs out with friends after class. He seems to have endless energy. Lin Weimian avoided him, but in the ridiculous daily collisions, he discovered his loneliness and scars hidden under his smile.
Jiang Chi seems to be cynical, but in fact he is under tremendous pressure from his parents' discord and high expectations. He wraps up his true self in layers of "funny" shell. Lin Weimian's path to pursuing his design dream was also full of thorns due to his parents' strong opposition.
Two teenagers who are also bound by their families, from the initial "dislike" of each other to gradually being attracted to each other. Jiang Chi used his sunshine to warm Lin Weimian's loneliness and support her incomprehensible dream; Lin Weimian used her delicacy and firmness to see through Jiang Chi's disguise and became his only confidant. They agreed to be admitted to a university in the same city and became each other's most solid support in pursuing their dreams. On the thorny road to the college entrance examination, they supported each other and grew together. In the end, they not only received the admission notice of their dreams, but also found the warmth that healed each other's lives.
