Sorry but i dont really understand this Chapter. o.O Is the Mangaka now streching this Manga or why is it not focusing on the Main Chars anymore? im not Interessted in the Side Characters,,,,,,,,,,
Sayaka is one of the central cast and has been the focus of chapters before. She's Touko's best friend, is in love with her, and is Yuu's principle rival I don't think it's a diversion to focus on her POV for a chapter.
I like it this way, it helps to bridge the gap between You and Touko's falling out, rather than jumping right into the resolution like a lot of other manga would do.
It's building that gay suspense, my dude.
