I Became the Master of Making Their Dreams Come True

(Multiple heroines + romance + no tragic protagonist + mildly sweet + slice of life)

Gu Yan, a college sophomore, accidentally obtains the Dream Master System. In short, he can earn rewards by helping people fulfill their wishes inside the System's instances.

What Gu Yan never expected, though, was that all the heroines in the instances were real.

A sweet girl with wine-red hair, incredibly clingy, who works alongside Gu Yan.

A simple-minded, gentle country girl, a little airheaded, who escapes famine with him in the late Ming dynasty.

A saintess living in the spiritual qi revival era, born with a mission and fighting monsters all alone.

When he saw each of them holding a cleaver and making him choose, Gu Yan panicked.
