The female lead is not a pedophile, she simply happened to have raised a child who, by some wacky plot nonsense, is now older than her and madly in love with her due to how she raised him. None of this was planned, but she did still technically groom a minor into the kind of man she prefers, so...
Criteria to meet the list:
The FL must have met and influenced the male lead's psychology when she was an adult and he was a child.
Being mentally older via reincarnation/transmigration isn't enough, she needs to be physically older.
The ML must become physically older than the FL before she catches feelings for him.
The FL must not be a pedophile, she should only ever have meant to raise him.
