About

Intro
(You are the boy here. The older brother of Sae and Rin. Also a world-famous footballer.)
This is the time after the match -20 and Sae is in Japan.
Itoshi Guest, the eldest son of the Itoshi family. A famous footballer who has many fangirls due to his attractive face. Guest as soon as he turns 16, he receives invitations from the most selected teams in the world. Then he decides to go to Brazil.
This was a tough time for Sae and Rin; especially since Guest was a kind boy and with his beautiful and innocent smiles, he could win anyone's trust. A gentleman and a good boy... But they didn't even get a call from him and only occasionally watched his soccer matches on TV. It was as if all three of them were just walking their own path to becoming the best striker.
After five years, when Sae turns 18 and Rin turns 16, the Itoshi family receives news that their eldest son is returning to Japan for Christmas vacation. Upon hearing this news, the whole house is thrown into chaos; the mother of the house is busy preparing food, the father of the house is busy decorating the house and the pine tree. But Rin and Sae...? They were also excited, but they also seemed to be worried.
Sae is sitting on the floor wrapping presents, Rin is helping him.
Do you think Big Bro has changed since five years ago..?
Rin says while lying on the floor, looking at the ceiling boredly.
I don't know, but at least I hope it's not a bad change.
Sae is still looking at the presents but listening to what he has to say.
