Warnings: The story takes place after the incident in Cuba and Charles is still walking, and none of the bad things have happened, the team is still together.
Scott Summers was new to the Xavier Institute for gifted children, he had recently discovered his mutation and with the help of his brother, Alex, took up residence at the Institute. While leaving the literature class taught by Professor Xavier, he bumped into a boy with (H/C), he was short and skinny but had the features of an angel. Both boys' books crashed to the floor.
- I'm sorry. – The shorter boy said immediately.
Scott still couldn't take his eyes off the boy's angelic features.
- Hey? Are you okay? - Said the boy a little worried.
- Of course, I'm sorry! I've been a little distracted, it's all a little new to me.
- Okay, I understand. Have you ever taken a tour of the mansion? - Said the boy getting excited.
- Professor Xarles showed me some places but not all.
- Come with me, I'll show you my favorite place. By the way I'm Y/N Lehnsherr.
- Scott Summers. – He stopped for a moment to reflect and said – Wait, Lehnsherr as the teacher?
- Yes, I am adopted by professors Xavier and Lehnsherr. So I think officially Y/N Xavier Lehnsherr.
- Nice to meet you.
- It's my pleasure! Come quickly, before my parents find me and ask if I've done my homework.
Scott was a little confused. His brother had already said that Professor Xavier and Magneto were a couple, but he didn't know that they had managed to adopt a son. With Xavier's powers it shouldn't have been too difficult to get the adoption paperwork.
The two boys headed towards the forest at the back of the mansion, it was still late so it was well lit.
- How long are we going to walk? – Scott asked
- Just a little more, lazybones, don't worry, we're almost there!
For twenty minutes the kids walked around and talked about random conversations, their favorite movies and books, what they liked to do in their spare time, favorite subjects and stuff like that.
After a long walk they arrived in an open place, the sun was not so strong that it could interfere with the vision. And what Scott saw in front of him, even through the red lenses, was something beautiful.
It was a clearing, with countless flowers, all spread out in a blooming field with a few trees shading.
- Come, you can lie on the grass and flowers here under the tree, this is my favorite place. - Said Y/N.
- Wow it's beautiful, what are the flowers?
- They are wisteria, I planted them myself, when I found this open space I couldn't contain myself in making everything more beautiful.
- Did you plant all this yourself? – Scott asked shocked.
- Well, I didn't use the orthodox way. - Said Y/N as he made a red rose grow and handed it to Scott.
- This is my mutation, I have control over the vegetation, over nature in general, but I focus more on plants. Papa says I can go too far with my gift, but Dad is afraid I might lose control.
- Papa? – asked Scott.
- Yes, it's how I say daddy in German, or when I see he's angry it's vater, and sometimes when I'm sad and sleepy vati.
- Do you know how to speak German?
- A little, my vater was born in Germany, so I have some German lessons with him.
- It seems incredible to have mutant parents who accept you so well. – Scott said a little sadly. And besides, thank you for the rose. Is it really red?
- Yeah! And forgive me I forgot that your lenses only let you see red. Close your eyes for a moment, please.
Scott closed his eyes and waited for the smaller boy's order to open them.
- Wow. Now it's more beautiful. What did you do?
- Wisterias are usually lilac but I changed them to red, so you can see their beauty.
- Didn't need to, didn't want to spoil your field of flowers.
- Don't worry, I keep changing them colors for a change.
And then came a calm, not awkward silence, just two boys lying in the flowers, relaxing and enjoying the sun. After a while Scott finally worked up the courage to ask.
- If I'm being rude please let me know, but how did Charles and Erik find you?
Y/N tensed a little, but relaxed soon after.
- Well, there was a time when the Brazilian government along with other anti-mutant governments developed a law that tested all newborns for the X gene, and I was lucky to be one of them. My birth mother didn't want to go through the pain of having to hand me over to the army so she left me in a dumpster. And by a miraculous coincidence, the X-Men were in Brazil rescuing mutants and dad felt me, he and vati were running to where I was. They always told me it was the purest love they felt when they looked at me. Since then, I'm their son, dad messed with some people's minds so that adoption can be legalized and I don't have too many problems.
- So... you've lived with the X-Men since forever?
- Yeah, it's quite fun actually. Obviously, they never let me go on a mission, but it's like we're all one big family.
As Y/N spoke, Scott blatantly stared at the boy's face and inadvertently said:
- I think you're the most beautiful person I've ever seen in my entire life.
Y/N's face immediately flushed.
- You're not bad either, ruby eyes. – Y/N said still amidst shyness.
Suddenly Scott realized what he said and sat up abruptly.
- I mean, you're nice and a really charming guy, I didn't mean anything else you know. You don't have to think I'm weird or anything.
- Scott, we're in a place where people shoot lasers out of their eyes, a boy turns to ice and do you really think sexuality is an issue here?
- It's just that I... I've never said something like that to any boy.
- And I'm glad I was the first. My father often asks me to welcome newcomers, but I don't know why, the moment we bumped into each other I felt the same connection I feel with plants. You, besides my parents, were the only one I introduced this place to.
- I guess this counts as a date then?
- Definitely not, ruby eyes, I'm a difficult boy you know? You need to take me somewhere that's special to you too... and face vati.
The last part definitely scared Scott, but he wasn't about to give up on the beautiful flower boy so quickly.
Later that night...
There was a noise at the door of Y/N's room and he knew it was vati.
- May I come in meine kleine sonnenblume? (my little sunflower)
- Yes vati!
Y/N was reading one of Lord Byron's works as he was getting ready for bed.
"I don't know how your father manages to make you read these things..." said Erik.
"Maybe you should give it a chance before you judge" Y/N said with a slight laugh.
- I noticed that you spent a lot of time today with Alex's brother, should I be worried about something?
- No, of course not. I went with him to the wisteria field.
Erik's eyes were surprised.
- I thought it was something that only your father and I knew about.
- I know... but do you know how I feel the vividness of plants? The sprouting of a flower? The germination of a seed? When we bumped into each other in the hallway I had the same feeling, and the first thought I had was to take him there.
- Are you sure about that mein prinz? (my prince)
The door opened again and this time it was Charles.
- Erik, don't get jealous, please.
- It's not jealousy, I worry about who our son hangs out with, you know it's a dangerous world.
- Yes my love, the world is dangerous, but here we are safe.
- Y/N - Charles said approaching his son's bed. “I don't like getting into people's minds without permission, but I guess I have to admit that like your vanti I worry too… and Scott is a wonderful boy, give him a chance.
- Is this serious? - Erik said indignantly.
- Erik I think it's time for you to accept that our son has grown - Charles said laughing.
- Okay, can you two stop embarrassing me and let me finish my reading? - Said Y/N.
- It's okay my love, I love you more than anything. Have a good night. - Charles said placing a kiss on his son's forehead.
- I love you too, daddy.
- Good night mein hundenbay, (my puppy), ich liebe dich (I love you). And let me know if that boy causes you any trouble.
- Alright vanti - Y/N said smiling - ich liebe dich auch (I love you too)
