Out of curiosity, I went on the series website. I click on a random chapter, I go two/three page ahead and I see two girl kissing.

Yeah I don't think the tags are lying... or at least not totally x)
That was not part of the canon story. The author likes to play around like always.
Or you may have clicked on a fan art chapter.
Thibk you might be wrong about that. Hong isn't the only one with a kickass girlfriend.
In desperate attempt to get all this politics and DOOM back on track: Hong's come quite a long way from her initial "we're just friends, okay?!" stance, huh?
No spoilers my friend. That character is still several chapters away, and I don't remember they kiss. The only canon mouth-to-mouth kissing I have in mind is the unconscious one in the mountains.
As for Hong's change, well enjoy that for now, yeah, for now. The author has some serious plot screws (I think twist is not enough here) in mind.
