I started watching this series for the phenominal cast. However, it turned out to be a lot more than just that. the amazing storyline, which can be violent to some audience, has the best message than any other kdrama i have ever watched. Nobody in this world can love us more than our parents, and to never forget that. it is a must watch to all teenagers especially! and, never lose hope or resort to suicide... if something doesn't work out, there are infinite other options and choices to make. so be confident and keep pushing forward! you can do this!
