The behind-the-scenes footage of IU and Byun Woo-seok's filming is making headlines again!
With even scenes of them poking each other's cheeks and exchanging heart gestures being revealed, it really feels like their sweet chemistry has come alive haha.

The atmosphere on set is bright and cheerful, so I can really feel that the two of them have great chemistry naturally!
