My best friend's girl.

Inuyasha and Darien grew up like brothers they were the best of friends since they were kids, they always had each other's back, and they shared everything, they did everything together, until they both reached the age of 14, and they were separated for many years 7 years they were separated because his parents moved him away leaving Darien all alone, but now all these years later, Darien has new friends and has a whole new life but now other than his secret life of Tuxedo Mask he runs into his old childhood best friend Inuyasha who has a beautiful girlfriend, Inuyasha's back in Darien's life, but things are much more complicated than they were before like when life was peaceful and they were kids but now they're both adults and a lot of things have changed and even they've changed they both experience new experiences and they've both changed. But now trouble is brewing in.

Kagome and Darien got along super well. After Darien truly insisted that they go on a double date. Inuyasha agreed with it. And Serena and Darien met with them. And such open the door for someone to fall in love with someone else.

Enjoy.
