So much hate >_< I get that her behavior is frustrating but as she just said "I thought that when I disappeared the story would continue normally". This assumption mustn't be necessarily wrong. Ibe already admitted her growing feelings in the previous chapters but realized 1.) that she is a maid (status difference), 2.) that she is an inserted side character i.e. possibility that she just ends up getting transferred back to her world and 3.) as it is often an issue with those types of stories that the former readers have either a hard time assimilating with the world as an actual person and/or that they are afraid to disrupt the world because irredeemable damage could occur.
Also, with all the stuff (be it gossip, expectations, ...) thrown at her in a short amount of time, I guess everybody would need to catch a break.
