I think the Big Mouth v. Big Mouse title confusion has been sorted out. The drama called Big Mouth is scheduled to air on MBC Fri-Sat time slot after Doctor Lawyer and today released the first official drama stills of male lead Lee Jong Seok. He plays the titular Big Mouth, a loquacious lawyer with a low win percentage who nevertheless seems to be happy with life and who wouldn’t since he has Yoona as his nurse wife. But after he gets involved in a murder case he’s accused of being the genius swindler known as Big Mouse and he and Yoona have to try and clear his name. That’s the short synopsis but I’m sure the narrative will be much more robust. The drama is from the PD of Start-up, Hotel Del Luna, and While You Were Sleeping so I know visually I will love it.
