Wow, the anime version was from 1990. It was shown in local TV (ABS-CBN) before and was my favorite cartoon as a kid. Ito ata nagmulat sakin sa mga love stories. Anyway, the Korean version was shown in 2005 and has almost the same plot where the protagonist has an unknown benefactor and which she called as Daddy Long Legs.
After watching the Korean movie, I was like “Yun na yun?” Maybe I just expected more.
