[Brothers Conflict] Why Are All My Friends Named Asahina?

As a screenwriter who has made a name for herself in the entertainment industry, shouldn't I be adored by countless young women and become everyone's favorite confidante? Wait, that doesn't sound quite right. So why do all my friends have the surname Asahina? As a handsome, dignified gentleman (is that really the right way to put it?), shouldn't I get promoted and a raise, become the general manager and then CEO, marry a rich, beautiful woman, and reach the pinnacle of life? Wait, I think I've got the wrong script. So why do all my friends have the surname Asahina? Do those two things really have anything to do with each other? If you don't like it, don't read. The characters will mostly be out of character. I'll try not to make them too bland, but good writing is a pretty mysterious thing =_=. Apparently, in the original story, the ninth brother Subaru ends up with Ema, so here I'll leave it up to you all to... I'm not breaking up Masaomi and Yusuke, though I might not write much about their pairing anyway. Hikaru will have almost no appearances. Yusuke is a good kid, and since he was the first to fall for Ema, I'm sorry I can't give her to you, but I'll do my best to arrange a beautiful future for you (fist pump). This story will end with a one-on-one pairing. Who it will be depends on how the story unfolds and what the readers think.
