In Qian’nan, where the plum rains stretch on, leaving everything damp and humid, construction supervisor Chen Mo moves south for love and buys a home. But his marriage to his ex-wife Lin Li falls apart after her parents interfere, plunging his life into darkness. The wheels of fate turn quietly, and one day, at the entrance to Misty Rain Alley, he meets Lin Xiao, a single mother. With her pale blue umbrella and gentle, water-soft eyes, she seems like a beam of light cutting through his despair. But Lin Xiao carries a dark past, haunted by the threats and control of her ex-husband, Zhou Qiang. Their growing closeness is bound to bring them into the path of a storm. As Zhou Qiang closes in, using financial pressure and violence, as Lin Li tries to make amends through her remorse but witnesses Chen Mo’s new bond taking shape, and as two children go from hostility to acceptance, becoming a link in their redemption, the scar on Chen Mo’s left chest aches faintly. Still, he risks his life to protect her. Amid the damp alleys, moldy rented rooms, and tangled snares of fate, he and Lin Xiao bring each other warmth and salvation. Love becomes their shield as they struggle through thorns and stubbornly grow under oppression, until their blazing hearts finally break through the deadlock. This is a story of broken lives and being reborn, an epic of souls rescuing one another from the mud. If he could live it all over again, facing the ruins of his marriage, the cruelty of fate, and the choice of whom to love, Chen Mo’s answer would still be unwavering: “I’d still choose you.” The plum rains will eventually end, and love will pierce every shadow.
