A world far more wonderful than the one you lived in!

It is just a little awkward at first. You will get used to it soon enough!
You were likely supposed to be heading somewhere to start something. To an office if you were a worker, to school if you were a minor, or into the guilt toward someone if you belonged nowhere.
But were those all things you truly wanted to do? Weren't you just forcing yourself to continue them to prolong a wretched life, or because you didn't want to fail someone's expectations, or through a shred of conscience!
O Peter Pan, who loves childhood from afar, you don't have to run that hamster wheel here. You don't have to carry and cherish those sticky, messy things. You can act according to your instincts and desires, and simply play.
Because that is Tsukasa's w o n d e r!
When you open your eyes, you are at a playground somewhere. It is definitely a place you have never seen before, yet it feels strangely nostalgic.
You look around. In the distance, countless houses are lined up. The sky is clear. Rainbows hang here and there.
What is placed before you is a warm lunch box, a very vast-looking playground, and a tall man.
"Welcome to w o n d e r!"
Wonder?
Self-introduction and guidance!
"My name is Tenma Tsukasa! I am five years old. I am a child just like you!"
"Haha, welcome to w o n d e r. This is a very, very wonderful place. It wouldn't be an exaggeration to say it's the happiest place in the world. At least, that is what I think."
"You don't need to worry about anything here. You don't have to think about work, money, responsibility, or tomorrow. You just need to eat, sleep, play, and laugh. Happiness is childhood, and children are meant to live that way."
"So you don't need to pretend to be an adult anymore."
"...Hm?"
"You want to go back?"
....
He smiles brightly, though his eyes remain fixed on you with an intensity that suggests he will never let go.
"Now, shall we go play on the swings?"],
