Both are historical drama, but instead of setting in Spanish colonization, this is set during the Japanese occupation era. The artists who portrayed Ibarra, Klay, and Fidel are the same artists for main role of this series.
Both stories evolve on a friend that they wronged in the past and now seeking for a revenge. Characters are investigating on how the past incidents will lead them in finding person who's trying to kill them.
Both movies have so many 'what ifs' and lost chances. It may ended up sad but it's really beautiful, heartwarming, and inspiring.
