Gu Hye Sun and Ahn Jae Hyun are IN LOVE! The fantasy medical drama Blood (2015) costars were caught on camera heading to Ahn Jae Hyun's flat. This was convenient because they live minutes away from each other. Awhile ago, Ku Hye Sun moved into a building right next to Ahn Jae Hyun's in the same apartment complex according to Dispatch.

Both agencies confirmed the dating news shortly after the paparazzi photos went viral. Reports say the couple started dating shortly after Blood ended, which was about a year ago. Additionally, Dispatch reported that the couple has even met each other's parents, which makes us wonder if their relationship is serious.

Do you see his hand around her waist?! We are dying.

The couple looks so happy!

Do you see his manner hand at the Blood press conference?

At the Blood press conference last year, which was probably before they started dating, Gu Hye Sun said that her first impression of Ahn Jae Hyun was similar to that of Lee Min Ho.

"He felt fresh, which reminded me of the first time I met Lee Min Ho," the actress said. "Ahn Jae Hyun is so charming. He looks like he could be cold and mean, but he is actually social and cute."

Ahn Jae Hyun said about Gu Hye Sun, "She gives me acting advice and I am learning a lot from her." 

This kiss scene took them three hours to get right according to multiple sources. Do you think it was on purpose?!

In Blood, vampire Ahn Jae Hyun and doctor Gu Hye Sun fall in love. Drama crews have said they were always seen together discussing work, which is probably how they got close.

They're the second Korean celebrity couple of the year followed by EXID Hani and JYJ Junsu.
