the girl I saw grows up

My name is Marcus Rossi. My family is Italian. We are best friends with the Sánchez family, a family of Portuguese origin. I met Matteo when I was 8 years old, and we became best friends. He had a very annoying younger sister known as Tina. She was 5 years old, an unbearable and spoiled little girl who wanted everything immediately. This stressed Matteo out, and he would always hit her and push her when the annoying creature entered his room without permission while we were playing, wanting to play with dolls. My friend always got scolded by his parents because she would always come out of the room crying. On the other hand, she was a beautiful little girl, with brown eyes and hair. We nicknamed her Paluchinha because, besides being very small and playful, she was chubby. But she grew up. The last time we went to Portugal, Matteo was of legal age, and she was only 15. She got involved with a boy her age. Her family knew and didn't pay much attention until something happened. She got pregnant by the guy through carelessness, the coward's family took him out of school and ran away, leaving him alone with his irresponsibility. That really irritated me because, besides that idiot being a jerk, he made her get beaten by her father, who almost killed her. Tina only didn't lose the child because Matteo fell on top of his sister, taking the whole beating to protect her. He may have hated her in childhood, but he didn't hold a grudge and didn't think twice about protecting her. That drove me crazy. I may have hated her in childhood, but seeing her carry a guilt that wasn't even planned was too much for me. I took her out of that house pregnant with a child I didn't father and took responsibility for the baby as its father. Heloisa's birth was very complicated because Tina was a minor. Today she is 5 years old and the story repeated itself; the little girl is identical to Tina when she was her age, and I am completely in love with the woman in front of me, whom I hated so much in childhood, and I was able to accept her when she became a single mother.
"I got home early from work today" I wanted to relax.

Today I am 25 years old and Tina was only 20. We are no longer the same children we were 5 years ago.
