Okay, so, like a lot of people here, i'm not a fan of this "going backward but with ice Kaguya" stuff. But, I suppose this is kind of a conclusion arc about all the indecision and hidden feelings of Kaguya. So, even if it's frustrating, let's wait and see, chapter 142 gave me the feel that this wasn't just for pointless drama. It's like Ice kaguya didn't realised things have changed and she have to evolve because over the top subtle trick like this won't work. After all, even if she's in love, she is pretty paranoïd and she's right to be so, so I guess she need a proof that she can sincerely trust Shirogane.
And the doomed words were finally spoken.
That aside, I like the "almost creating new personna because of horrible chilhood" theme of this arc, it can be pretty interesting (and give drama in a good way), and it's actually quite realistic (i've met some people who had a life similar to Kaguya's one and who ended up like her, or worst).
Anyway, wait and see. Akasaka never dispointed us, so I give this arc a chance.
