Gu Ye and Lin Chao are unrelated brothers. The elder brother Gu Ye is gentle and calm, and is a popular figure in the school; the younger brother Lin Chao is sunny and cheerful, but he hides something that he dare not express openly - he likes his brother and has liked him for a long time.
In the hottest summer of youth, the brothers' daily interactions were filled with cautious temptations, until an unexpected opportunity made Gu Cha no longer able to hide his feelings. While Gu Ye was shocked, he found that he had long been accustomed to his brother's existence and could not even imagine a future without him.
From escape to acceptance, from confusion to determination, their feelings quietly grow in the gaps of youth. Finally, at the end of midsummer when the cicadas were chirping noisily, they found the answer that belonged to each other.
Concept: Youth is a grand secret love, and love is a game for the brave. In the pull between worldliness and sincerity, they choose to face their feelings and no longer escape. The name of brother was once a bondage, but it has also become the gentlest bond - because true love never needs a reason, only courage.
