After Meeting Him in Person, I Became the Beloved Heiress of the Richest Family

DC + Damian + original heroine + one-on-one romance + pure love

In a city of crime, she encounters every kind of criminal.

A work-weary vigilante suddenly appears, tasked with helping a stray fawn.

She meets her online friend of two years in person, offering food, lodging, and company.

Her young online friend runs into danger, and a magic Batman appears.

She is adopted by a billionaire and becomes her online friend's big sister.

Then her life takes off.

On the surface, the Wayne family is America's most elite and top-tier star dynasty: aristocratic, stunningly attractive, rich and powerful, and at the pinnacle of high society. They seem to be a glamorous, luxurious family of privilege.

Behind the scenes, they are all superheroes, capable fighters who fiercely protect their own: a secret family guarding Gotham at night.

The story starts with family bonds, then moves on to a romance once they can legally be together.

Completely out of character. Original-work purists, beware: you might get knocked flying. It's DC, but you can enjoy it even if you haven't read the source material. Extremely out of character, with questionable values.
