she knows his deep desires, secrets and phantasies

He looks at her and smiles "well that's good, it means you didn't loose your memories"
she starts denying "no, i mean your inner self... i know how do you feel... what do you want..." then She blushes "how do you love me... too"
He notices that too and kisses her gently
then he starts looking inside himself and notice the same: phantasies, memories of eing together from her pint of view... her phantasies...
he couldn't believe it but now he could see they were sharing a link. now he knew everything about her... and in the same way she knew everything of him
They started sharing a life together as very close friends, knowing each other better tan anyone and sometimes noticing things of the other one, the other one hadn't noticed himself
strangely on this years, they decided to wait till they were 18 for having sex
they knew each other perfectly so hey didn't doubt how they should start
