Singer G.NA gave entertainer Boom a straight face.

On the episode aired on March 10 of KBS 'Birth of a family' G.NA, Boom, Hyun-a, and Si Wan made their appearances to greet a new abandoned dog as a part of their family.

On the broadcast, G.NA and Boom played the roles of a cute couple. Boom even joked around "G.NA, you must have wanted to film 'We Got Married' with me?” However, G.NA made everyone laugh by loudly singing with a straight face 'I'll back off so you can live better.'

Despite her strong refusal, Boom continued to bother her by calling her, 'wifey', 'you are attractive', and other names.

On the other hand, Boom danced 'Trouble Maker' with Hyun-a, the start of a 'Dirty Maker'.
