Lee Sung Kyung Opened Up About Working with Nam Joo Hyuk for Weightlifting Fairy

OMG, Lee Sung Kyung opened up about what it's like working with Nam Joo Hyuk on MBC's Weightlifting Fairy Kim Bok Joo...and we don't know how to process our emotions. READ: They've reportedly been dating for five months already, so we're 99.9% sure they already had feelings for each other during the production of the show. LOL!
In her interview with Grazia, the model-turned-actress revealed that it was a good experience working with her co-star, saying,
"Since Nam Joo Hyuk and I are really close, it was easy for me to get into character. It was nice and comfortable while filming. He helped me to be at my best condition."
Looks like they got too comfortable with each other that they actually fell in love. Hee hee! We mean, just look at these two working together:
*sigh* Why are these two sooo cute together? Just go ahead and let us die of kilig, #NamLee! ♥
