Earlier this week, the lead actors and actresses of tvN's upcoming drama 'Romance Is A Bonus Book' attended its press conference to greet fans ahead of the series' premiere!

'Romance Is A Bonus Book' marks actress Lee Na Young's first small-screen project in 9 years, after her 2010 KBS drama 'The Fugitive: Plan B'. Lee Na Young has been on a lengthy hiatus since her marriage to actor Won Bin in 2015, as well as giving birth to her first son in 2017. She returned to the big-screen through film 'Beautiful Days' last year. 

During the 'Romance Is A Bonus Book' press conference, the actors were all asked to pose for the press with the popular "finger heart" pose. However...

It seems Lee Na Young didn't understand what the "finger heart" pose meant! Her co-star Lee Jong Suk turned toward her to teach her just how to do the "finger heart"...

(〃ﾟдﾟ〃)... /Totally embarrassed/

She's so cute when she's embarrassed!

It seems that the poor actress felt so embarrassed about being in the dark regarding the "finger hearts", that she couldn't bring herself to do it for the entire duration of the press conference.

Instead, Lee Jong Suk made twice as many finger hearts for the both of them (*´∀`)

But they still did a hand heart together!

Netizens reacted with comments like, "She must not have come across any media content at all in the last few years! The finger heart isn't that new", "Wow is her face seriously that small?", "They are both super cute! Looking forward to the drama", "She is too too too too too pretty", "Lee Jong Suk's skin is pure pink...", "So jealous, Lee Na Young sees Lee Jong Suk at work and Won Bin at home...", and more!

You can catch Lee Na Young and Lee Jong Suk's new romantic comedy 'Romance Is A Bonus Book' beginning January 26 at 9 PM KST!
