Hanoian's Manga

I think Gun ending up with Hanmi doesn't make sense at all, considering their personalities. Gun x his brother makes the perfect stable molecule, no matter what relationship they have. The reaction between Gun and Hanmi would require a big bad catalyst. Hanmi and Junhuyk, on the other hand, are like sodium and water, too reactive and explosive that they kept trying to separate from each other. You see what I mean?
