The Stuttering Sweetheart of the Underworld Heir

He is an all-powerful underworld heir, the cold-blooded successor in a family line with only one heir per generation.

She is a stuttering librarian who grew up in an orphanage.

After an accident, she disappears without a trace, carrying his child.

Five years later, they meet at the airport, and three mini versions of him cling to his leg and call him “Uncle.”

“D-D-Daddy is... is... here!” the little girl stammers, pointing at the paternity test.

He stares at the 99.99% result on the report, then looks at her anxiously shielding the kids. “You stole my genes and ran off?”

“I d-d-didn't steal them... I just... b-b-borrowed them for a little while!”

The world's most advanced security system fails at his house, where the triplets always manage to sneak in.

“Big bro, what are you doing hacking into my study?”

“L-Looking for... Mommy's... p-pictures...” The eldest points coolly at his safe.

Looking at the three little troublemakers and her flushed face, the young master accepts his fate and pulls out the family's heirloom black diamond ring:

“Marry me. The kids can take your last name, spend my money, and... hit me whenever you want.”

“N-No... no hitting...” She waves her hands in a panic, but he pulls her into his arms. “Then you can kiss me instead.”
