See here is the thing with Ryuu
He loves Asuka, but he still has lingering affection for actor girl.
He can't satisfy actor girl cause she doesn't want to divorce her douce husband.
He can't satisfy Asuka cause he doesn't want to get married.
So what's he gonna get... NOBODY!!
If Ryuu doesn't make up his mind he's gonna lose Asuka. Cause believe me, Asuka is not going to drop her family values that easily.
