Reincarnation question

Hey guys I got a question so if you over 18 years old reincarnate into a baby's body and grow and have a child best friend who has feelings for you but they confess when you guys are like 17-18 but you saw this kid grow up. Would you accept the confession, how would you feel about it, does it feel like grooming or corrosion if you accept and if this childhood best friend said there an adult would you do the deed with them.
