In Qiannan City, which has a long and humid rainy season, project supervisor Chen Mo went to buy a house for Ai Nan. However, due to the intervention of his parents-in-law, his marriage to his ex-wife Lin Li broke up, and his life fell into gloom. The gears of fate turned quietly. He met Lin Xiao, a single mother at the entrance of Wuyu Lane. The woman holding a light blue umbrella and with gentle eyes like water split open his desperate world like a beam of light. However, Lin Xiao is burdened with the dark past of threats and control from her ex-husband Zhou Qiang, and their proximity is destined to lead to a storm. When Zhou Qiang pressed harder with economic means and violence, when Lin Li tried to make amends in regret but witnessed the bond between Chen Mo and Xinsheng, when the two children's transition from hatred to acceptance became the bond of salvation... The scar on Chen Mo's left chest hurt faintly, but he still protected each other with his life. In the damp foggy alley, the moldy rental house and the confusion of fate, he and Lin Xiao warmed and redeemed each other. They used love as a shield, struggled forward among thorns, grew stubbornly under oppression, and finally broke through and were reborn with a fiery heart. This is a story about brokenness and rebirth, a redemption epic of souls salvaging each other in the mud. If he had to do it over again, facing the ruins of his marriage, the difficulties of fate and the choice of deep love, Chen Mo's answer would still be firm: "I still choose you." The rain will eventually stop, and love will eventually penetrate all the haze.
