What I liked about George and Yukari is that it seemed like the relationship was a very different thing to each of them. It's not Great Towering Manga Love Against All Odds; it's Yukari's first love, and George is sweet to her and clearly loves her too despite being a giant freak. It seems real to me that she doesn't get him and that he's more okay with the situation, and I agree with you that her going to Miwako is great too.

Have you gotten to the disturbing part about Miwako and her guy? I don't remember when it was and don't want to spoil it. Get reading! :)
