I love them as a couple! What's make them more adorable is that Ken absolutely adores her and pampers her. You can tell when he is near her, he's absolutely mesmerizes and in LOVE. Even though Noi is older than Ken, Ken is a very mature man. When he speaks, you can tell by his tone of voice and boby language that he has a good head over his shoulders.
What I love about the two of them is that they are not afraid to express their feelings and show affection towards one another. They never made their relationship a secret, it was out in the open seven years ago, and it's still going strong with a baby on the way. That right there shows, "We don't care what others think, we love each other and our feelings matter the most." That's Love!
