Everyone envys their marriage, people's perspective of them is that they're perfect for each other. Theyre a match made in Heaven. That they fit each other. To people's eyes, they're like the female/male version of each other . But in the eyes of the couple, it's different for them. For them, they're just a regular couple who is deeply in love one another. 

To people it may seem easy to get to where they are now. But it's the complete opposite. Hardships, challenges, struggles were thrown at this particular couple. Fate was testing them but throughout all of it, they passed it. They got out of it together. Always holding each other's hands, never letting it go. 

In the end, they're Mr. & Mrs. Horvejkul. 

Or in other words, they're the couple that everyone envies. They're Nichkhun and Victoria Horvejkul.
