No Haru is, he is the eldest son. Takahito is Haru's twin little brother.
OMG.........!
Jajaja what part of the story are you following? ლ(´ڡ`ლ)
I couldn't find this manga and I was looking for it for quite some time because I didn't add this manga in my lists. ╮(￣▽￣)╭ But I now get a pretty good idea of what's going on now.
Good. I like where the story is line in up too. (●'◡'●)ﾉ
Wait...........Isn't Takahito the crown prince? What happen?
