I want to write an exchange of letters between 16-year-old boy and girl who met during the summer vacation. Create some possible background for these young people and briefly describe their physical appearance, character and some other characterizing traits.
First, let me explain some background.

Alex and Ava are both 16-years-old and have known each other since the summer holidays when they met at the beach. Alex was visiting his aunt and uncle in the area and Ava was volunteering at a summer camp nearby. Although they only had a few days to get to know each other, they quickly formed a close bond based on their shared interests in music and adventure.

Alex is tall and lanky with a mop of unruly brown hair and piercing blue eyes. He has a confident, easy-going personality and loves to make people laugh.

Ava is petite with a heart-shaped face and auburn hair. She is quiet and thoughtful with a creative streak, often making up stories and playing music in her free time.

Alex is an optimistic and adventurous spirit, always looking for an exciting new experience. He loves to explore and take risks, and is always up for a challenge.

Ava is more of an introvert, preferring to spend time alone or with a few close friends. She is incredibly passionate about music and literature, and loves to express herself through writing and playing guitar. She is also fiercely independent, and loves to take on projects that allow her to explore her own capabilities.



Now, an example of the letters:

---

> Dear Alex,
> 
> I hope you’re doing well! It’s been a while since we last saw each other, but I still think about our time together at the beach all the time. I miss our late-night conversations, and all the crazy adventures we had!
> 
> I’ve been busy lately, trying to get ready for the school year. I’m sure you’re just as excited as I am to get back into the swing of things. I can’t wait to hear about all the new things you’ve been up to.
> 
> Until we can see each other again,
> 
> Ava.

> Dear Ava,
>
> I hope you’re doing fantastic! I can’t believe how quickly the summer flew by. I miss you and all the memories we made together – I still laugh about some of the crazy things we did.
> 
> I’ve been pretty busy too, trying to get ready for school. I’m sure it’s going to be a great year and I can’t wait to hear all about your new adventures.
> 
> Until we can meet up again,
> 
> Alex.

Thanks. I need this 'cause I'm making a game on Godot 4. Can you make a script to make these letters appear on a screen with cool effects?
