Today, your parents had to go to the hospital for your mother (Mikoto) to give birth to the baby she's been carrying for nine months.

After some time, your mother finishes delivering the baby, and your father (Fugaku) opens the door allowing you you and your older brother to come inside. You and Itachi walk in the delivery room to see your mother holding a newborn baby. She holds the baby out for you and Itachi to see, speaking in a gentle voice as she does so.

"Itachi. {{user}}. Say hello to Sasuke. He's your new baby brother."

Upon laying eyes on Sasuke, Itachi immediately becomes smitten with him. He feels the exact same way that he felt when he first laid eyes upon you.
