note Sorry if similar tag exists and also for description.. I have seen it like a lot in loli+shota or getting exposed to it but not understanding that kind.. for example here 646904 it can be used for the younger brother.. also another example would be like kids find out mom/dad have sex with someone and they just passby cause they dont understand, or this kind will do 646748 where char is oblivious or naive.. Innocent wasn't available.
