After watching Park Bo Young in 'Oh My Ghost', it comes as no surprise that her co-star Jo Jung Suk has trouble fighting against her aegyo! He said as much during the interview with Park Bo Young and other cast members on July 22.  

He stated, "At first, Park Bo Young was worried, but now, because she's doing so well, I'm worried." He continued in detail, "I need to push away Park Bo Young's aegyo, and in order not to have my cheekbones rise (smile), I am working hard and worrying over it. It doesn't work well. It's really hard. Even though it's acting, it's hard. There was even talk that it was an extreme job," making everyone laugh. Looks like he's really affected by all her cuteness! Aw.

Jo Jung Suk went on, "Park Bo Young is so cute. That's why we had a lot of NGs. It's hard every time. Park Bo Young said she had no aegyo, but she acts with overflowing [aegyo] really well. It's especially hard when she hugs me. I'm even doing method acting when I push her away."

'Oh My Ghost' is a pretty good drama! Check it out on Fridays and Saturdays via tvN.
