I can feel that final game is supposed to be Chiyoko and Yukionna girl, but I can't help rooting for Sakine, yes she is doing manipulations and mind games, but so what, Yukionna treats Chiyoko like friend one minute and as her henchwoman second, tries to put hikies on her thighs not out of love or obsession but to see if Chiyoko having love partner, which is not her right to know or demand to know, Chiyoko isn't her toy or pet. At the same time Sakine does it because she love Chiyoko and is afraid to come clean and ask her out, which is not healthy, but is still out of love. Glasses is fine as chaos bringer for comedy and plot, but she still caused Sakine deep childhood trauma for years and doesn't seem to be any reformed
Anyway Sakine I am rooting for you! Even if there is typical romance signs of your defeat!
