[Bottom protagonist + irresistible charm + love rivals at each other's throats + everyone's darling + old-school Mary Sue (don't ask how they fell in love, they just did.)]
After pulling an all-nighter reading a novel and dropping dead, Cen Yin transmigrates into the book as its protagonist, who shares his name. Becoming the protagonist? Good!
But, damn it, this is a tragic romance... Bad! Bad! Bad!
Cen Yin is ready to go wild and give up, but the moment he learns he can come back to life by completing his missions, hope flares up again. So he gets right to work on them. But can someone tell him why the male lead, who was supposed to treat him with cold hostility, has gone completely out of character?!
