I would complain about all of this dilema that kusunoki has now, but, if you really think about it, her trouble seems to be really well fundamented, as a 11 year old, there wasn't much (more) that she could've done to fix this problematic issue that she had despite it not even being her fault, it was all a mix of selfishness and a lack of real trust between kusunoki's female friend and the selfishness of Ren, and out of everyone, the one that took the biggest hit, was the one girl that did not do ANYTHING.
In conclusion, now that she noticed that Moe likes shizuki, she's gonna be holding back on the (yet little) feelings she had for him, wich makes sense because she's scared to face the same problem as she did in the past (Moe would never react that way tho)
