So much hate for the cunning Ichika eh.. Personally, I like her now more than the usual "Onee-chan" traits she always flaunting in the past. That's her charm, at least for me. And believe it or not, snekking is not illegal. I believe she's doing these because she feels threatened by looking at ch. 74 and 75.
Now for Miku who thought she's the only one who loves Uesugi, after she saw a real threat right in front of her eyes, I bet she's going to exercise full scale attacks to Uesugi with her timidness. It'll be hella cute attacks lol.
