The World's Greatest Son-in-Law

On an ordinary rainy day, outside Jingxin Studio, the antique shop run by the Song family, their foolish son-in-law Chu Chen sat beneath the eaves as usual, gazing blankly at the rain. Inside the shop, his wife Song Yan was overwhelmed with family affairs. It seemed like a peaceful day, but the deliberate harassment from Song Yan's cousin Song Qingpeng, the arrival of a mysterious old man, and an attempted accident targeting Song Yan stirred up trouble. In his dazed state, Chu Chen relied on an inexplicable instinct to make tiny, seemingly coincidental moves that subtly affected how events unfolded.
