I really like shino-san already.
I think Saki might appear dumb but she's sharp enough to get what's happening, she just might be trying to believe in her due to how much she trusts shino-san buuuut~ I already think we won't have to wait long for the beans to spill out.
If Saki allow Naoya to 3-timing with Shino (which is high probability since she's her best friend), I don't think Mirika will just sit back and let that happen.
WAR IS COMING, PEOPLE!!
