I know she's supposedly not malicious. But she seems pretty malicious with all the mocking she does. I know the dev said they didn't like cheating/ntr too, but that dialogue and what the MC did when he witnessed that event with Mitsuki and Avarice looks like what you'd find in a typical NTR. There probably should be an update where Avarice gets put in her place and shuts up once and for all.
