"Who`s a good boy?" She said as tickled the two year old toddler in your lap. Laughing shrieks were her answer and the child she came to love as her own wiggled in delight.

A sudden knock on your door interrupted play time with little Angelo. She carefully placed him back in his crib and went to open the door.

The one who rang appeared to be a handsome man if a few years older than her with the most spiky brunette hair she had ever seen and sharp brown eyes that cut through like the sharpest blade.

"Hello." Even his voice sounded dangerous, as calm as it was.

"I am here to take my son home." He said before entering the apartment without asking any sort of permission.

"Your son?" She asked bewildered. When Bianca had called her at the hospital before she went in labor she had told her that the father was a one night stand that didn`t matter and she would rather forget him. Then after the birth she had managed to persuade her sister to sign over legal guardianship of the newborn baby to you. Once she had her nephew, now son in her hand she named him, since his birth mother didn`t. She had named him Angelo, since he was a little angel to you the moment you held him in her arms.

And now this man appears after two years.

Said man had walked straight to Angelos` room and was holding the small boy in his arms with a smile that held real gentleness in it. And now that the two were in the same room, she could see the similarities. The same face and hairstyle, only Angelo had inherited his coloring from his mothers side of the family. Her mothers ink black hair and the only thing he had from his birth mother, jade green eyes.

"Where is Bianca?" The man asked, lifting his gaze from his son from just as second and the warmth that had been there vanished when he looked at her.

"I don`t know." She said quietly, and watched fascinated and quite honesty a bit fearfully as fury leaked into his expression.

"What do you mean you don`t know?" The voice was deathly still, and she knew the only reason why she wasn`t in immediate danger was because he was holding his son. However that spoke nothing of afterwards.

"She left the hospital as soon as she recovered and was deemed healthy by the medical staff." She continued to explain.

"And what about my son, she didn`t think to take care of him?" The anger in his words scorched in the air, if they could actually drip acid, there would be a hole in the floor by now.

"She wanted to give him up after she delivered him." That had been the wrong thing to say, his anger was almost palpable.

"But I convinced her to sign guardianship over Angelo to me. Since Bianca said she wasn`t really interested in having children."

Turning to look at her the man spoke.

"You raised him." It wasn`t a question so she could only nod.

"How? You look to be even younger than Bianca, how did you afford to look after a child when you would need living expenses and I haven`t seen any other presence in the household.

"I work from home. And the small trust fund our parents left behind for me and my sister helps."

"Bianca never said anything about a rust fund."

"I imagine she didn`t, since I am willing to bet that she spent hers a long time ago." Seeing as Angelo was starting to get fussy she approached the man only for him to narrow his eyes at her.

"He needs to get his diaper changed, then get fed and have a nap otherwise he will be cranky for the entire night and spend it crying." with that said she approached him again and gently took her son away to the small changing station where she made quick work of the used diaper which was soon replaced by a new one. holding the now slightly calmer child in her hand, she made her way into the kitchen, where the bottle that she set to be warmed up was waiting to be used.

Testing the temperature of the bottle against her wrist, she deemed it satisfactory and positioned Angelo so he could get his meal. The man silently watched this from the sidelines.

Once the small child was asleep in his crib the two of the sat down to talk.

"So what do you want now?Why did you show up after all this time?" She asked him.

"I want my son with me, where he will be safe. I didn`t even know he existed three days ago!"

"But Bianca said you didn`t want anything to do with the baby."

"Bianca thought that packing her bags and leaving while I was away counts of breaking up. She never told me she was pregnant. I want my son to come home with me."

"You cant! He`s my son too! I don`t want to leave him. By all legal rights I am his mother." she said.

"I`m not saying you should leave him." his voice calmed her down immediately.

"I am saying you should marry me." That made her pulse quicken for several reasons.

One he was incredibly handsome, easily the most handsome man she had seen in her life.

Two he was asking her to marry him, those words alone make heart rates speed up.

Three and in her case the most important he was the father of her sisters biological child!

"Are you out of your mind?!" She whisper shouted, in order not to wake Angelo.

"No I assure you I am quite is just as you said, you are his legal guardian and mother while I am his biological father. Neither one of us wants to part with him so the only solution would be to get married, people will assume you are his birth mother due to him looking more alike to you than your sister with your black hair and her blonde one."

" Our mothers hair color." She muttered stunned.

"Yes, people will only assume I had him with you and found out after he was born and decided to marry you so the boy could have a full family when growing up." He let a smirk to grow on his face making him look like a lethal predator going in for the kill.

"Besides as the Don of the Vongola, I can assure you legalness means nothing in the under world."

Oh dear God, Bianca what have you done?
