The flow of their relationship is so natural. Even when one of them said the L-word, it was accepted as something given. Not that they took their bond for granted, it's just that they were too aware of how much they cared for each other.

I've seen some people hating the MC for how he behaved, but personally, i think the story and how the characters responded to things are pretty realistic. Considering how both MCs were best friends long before they started dating, i think it's to be expected that they carried behaviors from where they were just friends to their love life. And that's exactly what the MCs did.
