Cupid's Chocolates

爱神巧克力ING...

Jiang Haoyi, an ordinary high-school freshman, finds himself swarmed by classmates he barely knows after every one of them confesses her love at once. Time freezes mid-chaos and a self-styled God of Love appears to explain the cause: a chocolate cake Jiang ate first, which makes any girl who tastes it afterward fall for him. He spends the series trying to undo the spell and survive the harem it created. This is a Chinese donghua.
