[All] IU ♥ Byun Woo-seok, I heard they burst out laughing just by making eye contact haha. Their chemistry is no joke.

Hearing that IU and Byun Woo-seok burst out laughing just by making eye contact, I can really imagine the atmosphere on set haha.
Seeing as they even said "it’s not easy," it feels like their chemistry is so natural.

If it's a combination that makes you keep laughing even while acting, it makes the viewer's heart flutter even more.
I think this would definitely be a fun highlight even if captured exactly as it is on screen!
