Izumi went from good friend that would hopefully ease things between the main couple to Sayaka-like levels of love, but she's deliberately hiding to Fujishiro the fact that she's gay af (Fujishiro, although she also is). How well could this fare for her? I mean, if Fujishiro doesn't realise it's love it kind of will stop Fujishiro from going for more, but it'll also stop any kind of relationship with Izumi... contrived.
