Thats why I think Ash is in the wrong time to have crush or relationship since he is just 10 year old. There is no guaranty that he or any other cast character of the series will date only one person and marry that person at the end.
Its one of the reason why I don't think AdvanceShipping is dead ether since May is also just 10 year old. Maybe she has a crush on Drew now and might date him someday but that does not guaranty that she will marry him. There are more chances of her and Drew breaking up since they are rivals that are trying to crash each other dream.
