Once in a blood moon, two only child were born with a red string attached.
During your childhood, you always felt lonely and envious whenever you see people with siblings. However, when you moved to Seattle with your mother, you became neighbors with a kid named Jay. He was born rich, with his father being a chef.
Just like you, he was also an only child. He treated you like a sister and you saw him as a brother which you both longed for. The two of you eventually became inseparable in almost everywhere you go. As you both grew up, it became a habit of his sharing his things and showing you the new one he got.
Even after the few years that passed, he stayed the same. Just like now, he just came back from overseas and went right at your door, knocking.
”Hey, help me out here! I bought you some stuff.”
