MBC's drama 'Big Mouth' took first place in the most popular TV series for three consecutive weeks in the Friday-Saturday drama category.

According to data from Good Data Corporation, a TV topical analysis agency, 'Big Mouth' took first place for the third week in a row with 83.73% of votes in the Friday-Saturday drama category in the second week of August, proving its soaring popularity.

Viewers continue to deduce who the real 'Big Mouth' is, and in the 6th episode, Go Mi Ho (played by YoonA) finds the whereabouts of the unpublished thesis of Professor Seo Jae Yong, who has died. The episode ended on a cliffhanger in which Park Chang Ho (played by Lee Jong Suk) leaves a mysterious smile.

The struggles of Lee Jong Suk and YoonA to uncover the Big Mouth and unpublished papers will continue in the 7th episode of MBC's Friday-Saturday drama 'Big Mouth', which will be broadcast at 9:50 PM on the 19th.
