Man, this is the first time I feel obliged to write a review of a work, I think that just like everyone else in the comments, we are surprised by this development of events between Esti and the old man there, and despite there being a page in one of the chapters that apparently showed that Esti liked Sebastiah (old man), it simply wasn't clear at all, and that's exactly what has everyone pissed off or at least discouraged from continuing to watch this work after that, after all, since the beginning of the story the author doesn't show this "plan" that Esti and Noah (MC) were planning, and it seemed that Esti really loved the protagonist, with all those scenes of her risking herself for Noah and even getting jealous when she finds out he went on a date, and I simply can't stand all this development being thrown in the trash, like, if the author wants to do some incestuous stuff, okay, fine, it's not like there aren't works that have already done that, but the problem is not making it clear from the beginning of the work, with I don't know, at least a small moment in the manga of Esti and Noah talking about this plan, and preferably this should have been shown within the first 5 chapters, seriously I really got completely discouraged after this poorly done and horrible plot twist, it's as if I created a manga entirely about a couple between a boy and a girl, with several cute and romantic moments, so that in the end the girl only likes the boy as a "friend", everyone hates this type of situation, whether in fiction or in real life.
Note: I, like another person here, created an account just to criticize this aspect of the work. I apologize if there is some writing error due to the use of Google Translate, or if I broke some kind of rule by giving spoilers of the work, but I really wouldn't recommend you spend your time creating expectations for a couple that was formed from the beginning of the work, only to be broken so horribly at the end.
