After the Silly Little Qingmei Returned, He Regretted It

[Revenge, heroine, darkening, sinister, sober, secret love, sweet pet, doting wife, super beautiful] Seventeen-year-old Shen Nianwei was hit by a boulder in a landslide in Yuntai Mountain while trying to save his childhood sweetheart Gu Tingchen. She saved her life, but she remained in the cognition of a child forever - her speech was vague, her eyes were confused, and she became a "fool" who needed Gu Tingchen's "charity" and care. At first, Gu Tingchen took her home with a bone-crushing guilt and took good care of her: feeding, bathing, telling stories about their past, and saying in front of relatives and friends, "I will get married when she gets better." Everyone believed in this deep affection, including Shen Nianwei who secretly hid the brush and couldn't even remember his own name. Until Gu Tingchen was admitted to University A and met Su Qing. This girl, who smiled with tears in her eyes, stuffed candy into Shen Nianwei's ears and whispered in Gu Tingchen's ear: "Nianwei hid my mother's bracelet. Does she hate me?" "Look at her messy drawings. Line, it seems to be written to another boy..." She induced Shen Nianwei to grab the cake at Gu Tingchen's birthday party, watching her covered in cream being laughed at by the guests, but turned around and said to Gu Tingchen, "Nianwei just wants you to pay attention to her too much." Guilt wears off into impatience through repeated provocations. Gu Tingchen started to lose his temper with Shen Nianwei. He would slam the door and leave because she soiled her shirt. He even didn't even give a warning when Su Qing said "take her to relax". It wasn't until Su Qing deceived Shen Nianwei into an abandoned factory on the outskirts of the city and watched her fall down the stairs being chased by wild dogs that she pretended to call to report the news. But no one expected that this fall would unexpectedly shock Shen Nianwei's mind.
