Ah-ran's elder sister is the product of Kangja's teenage accident with Ahn Beom. Being alone and not knowing what to do following her trial, Kangja ultimately sends off her first child to be adopted. Fifteen years later she seeks her out to explain why. Ah-joong was adopted into a crime family and takes after the way her mother was in high school, always causing fights and getting into trouble. Although she and Ah-ran are two years apart, she was held back twice and attended remedial school to "better her attitude". Instead of Kangja dressing up as a student as in the drama, Ah-joong transfers into Myeongseong High School to punish the people bullying her half-sister. She becomes the one to dig into what's really going on at the school. Angry Mom AU, pairings: Go Bok-dong/OC, Ah-ran/Sang-tae, Kangja/No-Ah

I felt this was a little simpler to write and more believable than a mom going undercover as a student. Plus I really love Bangwool/Bok-dong but it just doesn't seem like it will work out no matter how I look at it. This will follow almost the exact plot of the drama, aside from the change of the lead from Bangwool to my OC Ah-joong and a few other things. The plot and pictures to not belong to me.

Red Velvet's Joy (Park Sooyoung) was my visual inspiration for my OC, since Joy and Kim Yoojung (the actress who stars as Oh Ah-ran) look similar.
