Honestly it is too good to be a short web drama. Don't let the low average score scare you away, as there's much more depth in this story than it appears at first. Girl's War is the second web drama part of a  "T-Scope trilogy" but other than the app this story stands completely alone. It's about a reality show with idol trainees in the vein of Produce 101, but things get dark really early.

Considering the premise, I'd say Ryu Hwayoung is both the best and the worst actress to play the main role, but no matter how you feel about her real life persona I think she nailed this part. Girl's War could have been great with a bigger budget for songs and/or as a longer drama, but it's still really good. Very much worth a watch.
