I Love YouWo Ai Ni
Sa Rang Hae
Obviously I'm missing quite a few, and my foreign film watching is pretty limited. Feel free to add on any more that you know of and, hey, even name the languages each of these are in! (Albeit, I'm sure most of them are pretty easy). =)
And, while you're at it, if you're lucky enough to have someone who loves you, make sure to let them know!
