Sohee takes her new career very seriously! The former Wonder Girls member-turned-actress ignored the cold temperatures outside and focused solely on her scene in the latest still from her new drama Heart to Heart. In the tvN series, Sohee portrays the character Ko Se Ro. She is the younger sister of Ko Yi Seok (Chun Jung Myung). Her young, carefree role was on display in the relaxing swimsuit scene.

"It rained and the temperature suddenly dropped during filming. The weather made it difficult to film in only a bathing suit,"  the production company told the media yesterday. "She was probably very cold, but she did not show any signs of difficulty during filming. She was enthusiastic."

When a prosecutor discovers he has months to live, can he turn his life around and tear down corruption? Find out in the gripping melodrama Punch:

Heart to Heart is about a young woman named Cha Hong Do (Choi Kang Hee), who is incredibly shy. Her severe blushing is evidence of her social phobia. After her grandmother dies, Cha disguises herself as a senior citizen and begins working as a maid.

What do think about Sohee's incredible work ethic?
