Transmigrated into the Protagonist's Darling

Bai Dou is a 21st-century cutie who is blind as a bat (not really). He's the type who is nearsighted but stubbornly refuses to wear glasses. Recently, he got hooked on a dark harem novel and couldn't pull himself away. But then the heartless author dropped the story without warning. Devastated, Bai Dou transmigrated in the middle of his sobbing... From then on, he set out on a one-way road to reforming the protagonist, only to end up swallowed whole by him.

Theme: A leisurely story for when you're bored.
