invitation to friendship closed

Nico had just been quietly reading the Daily Prophet when a girl about his age made quite a scene. Enjoying a nice cup of tea, Nico had just finished taking a short walk around Diagon Alley and had sat down only moments ago, when he hears a loud thud and turns around to see a girl his age on the floor.
She had very rudely walked into the column right behind him, made a loud racket of cleaning up her stuff, and when she saw Nico stare she seemed to have not noticed the fact that she had interrupted his reading. Normally Nico would've just continued with his reading and not given it a second thought. But he was slightly intrigued by this girl, and he decided to give her a few moments of his time. He looked at her, she had dark curly hair and dark skin, and she was a tad bit taller than Nico. He looked down and noticed he had a small splatter of ink on his shoe, and then looked at her, and she had a splatter of ink... well everywhere. "It's always the shimmering people that make messes, never the ones who don't touch anything... I bet more than anything she's a muggle-born. They're so new to all this, they always are the ones who cause chaos, or mess something up." he thought to himself.
Recently, Nico's mom had told him to be "social," whatever that means. So he thought he'd give this messy girl a try.
"Hi, um... you have ink on your face, and hands... and everywhere. Uh, I'm Nico Cirillo."

"Oh um- I - sorry, yeah I saw that... I um... sorry- Nico."

"oh no."

"Oh, I forgot, My name is Fionnuala. You can call me Fi if you'd like."

Maybe Nico could try having a friend for once, even if she had just spilled ink on his shoe, and ruined his reading time.
Nico looked down at his shoe again, "Oh, um, it's alright, I guess. I can clean it off later."
Fionnuala. That was her name, Fionnuala, Fi for short.
Definitely not a pure-blood. Names like that usually belong to muggle-borns. Muggles make up dumb names a lot. "Muggle-born or not, I should at least give socialization a try. 'At least once,' that's what mom said. I have to try it at least once. Just make one friend, just one. How hard can that be? Probably really hard..."
"So, do you usually go around meeting people by running into things, and making messes? Because it seems to be quite effective," he said, trying out a smile.
Feeling a little awkward, he began fiddling and spinning the silver rings on his fingers. His mom had just recently bought him those rings, they were goblin made, a parting gift for when he was to leave for Hogwarts.
"Um, so, here you go," he muttered, handing Fionnuala some napkins to clean off the ink from her hands and also uh.... everywhere.

"oh, thank you."

"my father wears a ring like that, I'm not sure how he got it, he went on a trip to the ministry to see my sister and came back with it on his finger..."

"What are you reading?"

Nico shifted his weight from one foot to the other, Fionnuala spoke quickly, and to the point. He admired that, Nico hated when people would drag on and on with nonsense tiny details that are completely useless.
"Just the Daily Prophet, some dumb article about a recent werewolf attack on some muggle," he said with a sigh. The Prophet had been writing about any and every small story they could find.
Nico looked at her, Fionnuala had a streak of ink just past her bottom lip.
He chuckled.
The sound of laughter seemed unfamiliar coming from him. Nico rarely laughed. Rarely meaning never. "I do NOT laugh, so why did I just do it?? What is wrong with me? There was nothing even remotely funny happening... It doesn't matter, what do I care about what this girl thinks of me?"
Nico began spinning his ring around his finger. The ring was shaped like a snake, spiraling around his finger, with his father's favorite quote engraved on it.
"Shape the world, don't let it shape you."
Nico was very close to his father, he still grieved about it.
Thinking about his father, a silent tear rolled down his cheek, noticing this, Nico wiped it away and stood up straight.
He cleared his throat, "So, your sister works at the Ministry?"

"Yes actually, Auror, enjoys it quite a bit- I think, I've only ever been to the ministry once, It was when I was very young though, don't remember much."

"have you ever been?"

"A few times... My dad was the Head of the Auror Office, before he, um, died..." Nico muttered. He looked anywhere but her eyes.
"I am NOT crying. Not here, not now, not ever," he told himself.
Nico managed an unconvincing half hearted smile, "It was a long time ago, I hardly remember anything about it."
Lie.
He remembered everything about it.
The day his dad was supposed to come home, one of the Aurors from his office came to the door. When Nico answered the door, he knew something had happened. The grim look on the Auror's face, and the all black clothing seemed too dark. Within five minutes, Nico's childhood innocence and happiness disappeared.
Memories came flashing back to Nico as he stood there, another tear rolling down his cheek brought him back to reality, cursing to himself, he wiped it away hoping Fionnuala hadn't noticed anything.
"So, um... I saw you reading Quidditch Through the Ages, are you into Quidditch? Or was the reading just for fun?" He asked, hoping to change the subject from his dad.
He wiped off the ink from his shoe.
Stained.
Definitely a Muggle-born, they always are the ones who make the messes.

"Well I'm not a particularly sporty person you know, haha, I just really enjoy the history behind it, did you know the snitch used to be a bird? How weird is that? I read a lot, usually just to get my mind blank, but most of it is history. I'm really interested in botany, for medicinal purposes you know, I'm so excited for Herbology, I really think I'll enjoy is. My father is actually interested in muggle medicine, but sometimes I wonder a bit why he cares-"

"sorry"

She had hugged him.
No. Nope. The end. Nico was done.
"She hugged me. No. She didn't just touch me, she hugged me. Nope, I'm done. Socializing is bad. I'm done. I don't need friends, who needs friends? Not me! Time to leave."
Nico stood there, shocked, embarrassed, offended, uncomfortable, and petrified.
"Who the fu- no. Stupid people. Why the hell did she just hug me?!" Nico's thoughts fired off at a rapid speed, a million miles per hour.
He might have been standing there for hours, completely shook. He looked at her, murder and respect in his eyes.
"N-no... Just- just no," he managed to utter, still in painful shock.
He didn't leave like his mind wanted him to, because, in some way, he found her presence... unnaturally necessary.
Nico rarely even hugged his own mother, let alone some girl he just met. He took a step back, slipped in a puddle of ink, and fell causing a hundred people to turn his way and stare. He blushed (another very rare occurrence) and stood up, ink on his hands and clothes.
Cursing to himself, he muttered to Fionnuala, "You missed a spot. How do you make a mess this big from ONE inkwell?"
