I'm thinking about Sephiroth being cursed into an infant. He'll be pampered when found by the right person (eg Cloud, Aerith, Cream, Nyandola...)
He'll grow a year in a day, so the curse will last until he reaches his current age.
In his baby days, he'd be fed with milk and other baby foods.
Kid form, he'd be playing with other kids or his friends or with Cloud or Aerith or Cream or Nyandola whoever wanted to be friends with Sephiroth.
With Cloud and/or Aerith, he'd be cradled gently, taking care of him with their heart.
With Cream, he'd be playing with her, learning how to draw, bake, and anything else, or even making pumpkin soup during halloween, or his birthday, or almost everyday
With Nyandola, he'd be taught how to play music, sing and even introduced to adventures and stuff
Don't mind me being too talkative about it, just daydreaming about Sephiroth having a happy childhood🥲
