Quick Transmigration: The Pure and Alluring Ex-Girlfriend, With the Male Leads Fighting to Be Her Dogs

Quick transmigration + all male leads are devoted + beloved by all + white moonlight + 1vN + love at first sight + a lifetime in each small world + competition for her affections + seduction + romantic showdown

World One:

The gentle CEO male lead always gives his ex-girlfriend limitless understanding.

His ex-girlfriend seems pure on the surface but is actually a sexy woman. So after they break up, it's only natural that his friends and his junior get captivated by her, too.

World Two:

While sharing a rental with a rich heir who ran away from home, her ex-boyfriend, who was supposed to have died in a car accident, comes back.

After her ex-boyfriend died, she moved in with the rich heir. The neighbor who worked as a repairman was nice, too. They were having a happy New Year together when her ex-boyfriend suddenly returned... What a way to have a ghost show up during New Year!

World Three:

At her ex-boyfriend's home, she tutors his client's child.

Why do his friends keep dropping by? Why won't his client's child let his ex-girlfriend leave? Why does he still want to get back together?

Worlds Four, Five...

The small worlds don't necessarily appear in order.

Apart from the ex-boyfriend, all the male leads share one thought:

Sorry, your ex-girlfriend is mine now.
