with all respect to "psychological development theory" it all depends on the said person individual. I don't like generalizations about age, don't you ever heard the saying "age is this a number"? and I will say he is not that "childish" as you make him out to be, you can't build a whole private business of you are childish. and he even the manger of the whole thing, so no. he actually very mature for someone his age, much more then many people I know past their 30.

the opposite, I feel the uke takes their relationships lightly if he believes what his mother say about him instead of believing in his own boyfriend. he says it will be fine cause he means it, it does not mean he takes it lightly or not. he actually much more care about their relationships and almost kill himself in work to make uke happy. so no it's not empty words at all. read again all the Seme did for him, you can't say he isn't serious.
Blonde is really childish. Or naive. ... A lot of difference in age isn't good. Esp.if ur partner 20+. He s still boy, while u re the men already
