Top architectural designer Jiang Yubai, burdened with the shadow of his original family, hides all his tenderness under a cold shell, and has been secretly in love with Shen Xingci for seven years.
Freelance photographer Shen Xingci, who suffered from congenital heart disease and was said not to live past his thirties, used a quarrel as an excuse to leave his hometown in order not to drag down his sweetheart, and carried his illness alone through the long years.
Seven years later, fate reunited the two as work partners. In the ambiguity of reunion, they dismantled each other's disguises, healed their wounds, and became the only light in each other's darkness.
Jiang Yubai's insomnia was alleviated by Shen Xingci, and Shen Xingci's fragility was tenderly accepted by Jiang Yubai. The two-way secret love was finally about to be broken. They thought they could finally seize the belated happiness, but they did not expect that Shen Xingci's body was already exhausted.
In his last moments, he expressed his secret love in his last words, and he spent the rest of his life practicing his longing. The building named "Xingci Tower" became their agreement that spanned life and death and could never be fulfilled.
Purpose: 1. Explore the eternal proposition of "love and regret" - some love, even if it goes in both directions, cannot withstand the impermanence of fate. 2. Interpret the deep meaning of "redemption" - even if the ending is tragedy, the encounter and healing of each other bring light to the gloomy life. 3. Pay tribute to "silent affection" - secret love is not cowardice, but the protection and fulfillment hidden in the details.
