It's headline news when star couples admit their real-life romances, but many fans have already caught on to the stars' strong chemistry on the screen. A great example is Weightlifting Fairy Kim Bok Joo's Lee Sung Kyung and Nam Joo Hyuk, who just announced their dating relationship. Have you noticed the undeniable sparks in these dramas?

1. Scarlet Heart:  Nicky Wu and Cecilia Liu have really set the goal. They were attracted to each other while filming the famous time-travel drama but held themselves back from falling in love immediately. To fans' delight, they eventually dated in real life and got married.

2. Blood:  Gu Hye Sun and Ahn Jae Hyun married in May 2016. The stunning news did not surprise fans of the romantic vampire drama. The couple confirmed that they developed feelings during filming. Their kiss scene reportedly took three hours to film!

3. The Princess Weiyoung:  When Tiffany Tang and Luo Jin revealed their true romance on Tiffany's birthday, on December 6, 2016, fans were overjoyed to confirm the extreme chemistry they already spotted between the on-screen royal princess and prince.

Does it also make you wonder about Cheese in the Trap, where the two young actors starred in support roles? 

What makes these dramas really special is that it's usually rare to see real-life star couples star again as on-screen lovers.

Are there other dramas that should be included in this list?

Which on-screen couple do you think should date in real life?
