(Brothers War) Why Do All My Friends Have the Last Name Asahina?

As a well-established screenwriter in the entertainment industry, shouldn't I be popular among thousands of girls and become a friend of women (wait, something seems wrong)? Why do all my friends have the last name Asahina? As a gentleman with good looks (this is how to describe a real man?), Shouldn't I be promoted and get a raise, become general manager, serve as CEO, marry Bai Fumei, and reach the pinnacle of life (wait, it seems the script is wrong)? Why do all my friends have the last name Asahina (are there really any necessary connection between the two?) If you don't like it, don't read it. The characters are basically broken. I try not to be stupid, but the writing style is really mysterious =_=. It is said that Kuono Subaru and Ema got to the end in the original work, so please feel free to do so here. . . Yaya doesn't want to split it, or maybe it's not possible to write down their cp. The number of appearances is close to zero. Yusuke-kun is such a naughty boy. As the first child to fall in love with Ema, I'm really sorry that I can't give you Ema, but I will try my best to arrange a beautiful tomorrow for you (make a fist) This article will end with a 1v1. The specific target will be determined based on the direction of the article and the opinions of readers.
