A child or adolescent trying an image change to be noticed isn't that different from, say, picking up a hobby, for similarly "superficial" reasons. It doubles as experimentation with what kind of a person she wants to be. With moderation, I think this is pretty harmless. This kind of negotiation between wanting to be something that others like, and wanting to be authentic, is something everyone has to deal with, and a 3-page Twitter mini manga should not be expected to unpack all of this.
I would add that Kaho's girlfriend calls her cute in the present. Whether this is the same girl from Kaho's childhood, or not, this implies that she doesn't just see Kaho as a prince-replacement (though the chapters before should have proved this), so the whole relationship doesn't entirely hinge on Kaho's looks.
