There's a good reason why Sean and Jung Hye Young are one of the most envied celebrity couples around.

In celebration of 'Married Couple Day', Sean expressed his gratitude to his wife of nine years. He tweeted on the 21st, "A married couple. Two who live two separate lives, and then become one, looking towards the same future and living one life. Hye Young, thank you for looking towards the same future and living the same life as I do," along with a couple of romantic photos.

Sean didn't hesitate at all to show the world how much he loved his wife. He continued, "LIVE TO LOVE. 24 hours a day is too little for us to love each other. I love you more today! I'm more happy because I'm with you today! I'm more thankful for today because of you!"

Netizens commented, "I really want to be like this couple. I hope you're always happy," "The photo and your words are so beautiful," "I'm jealous of Jung Hye Young and Sean," and more.

Do his words make you cringe out of embarrassment? Or do you think they're romantic?
