On the MBC Wednesday/Thursday mini-series "Angry Mom" broadcast on Mar. 19, Jo Gang Ja (played by Kim Hee Sun) transformed perfectly into a high school student.

Gang Ja straightened her curly hair so that she had nice straight hair. This was so that she could disguise herself as a high school student. In the drama, her daughter Oh Ah Ran (played by Kim Yoo Jung) had been beaten by gang members and was a victim of school violence. To find the culprit behind the abuse, Gang Ja had decided to go into school herself.

After making this determination, she went to her high school friend Han Gong Joo (played by Go Soo Hee) for help. Gong Joo made sure that she did everything in her power to make Gang Ja look like a high school student.

At this, Gong Joo said, "I think it's a stretch to make you look like you're eighteen. Let's say that you suffered from a heart illness and had to repeat a year or something." Moreover, she said, "I'll be a mother instead of Kim Hee Sun's mother because we went through tough times as a child." With this, she was a staunch support of Gang Ja.

The transformation marked the official start of the plot as viewers are excited to see what comes next.
