The Korean Version of Umi is Kim Min Ji as Jang Yu Mi

RECALL – “memory lane”
The Live Japanese Version of Nakashima Yumi was played by Erika Toda ( of Death Note)
And remember the taiwanese version Meteor Garden 2 – Michelle Saram as Ye Sha (a totally different Umi from the japanese version, because she’s a bhutan princess in the drama).
