Of course, it is romantic to say I love you in different languages. It is the language we have spoken since the time we take birth in this world. To pass on that love in a different language is nothing short of beguiling. If you are willing to go the extra mile of learning a few words in a different language to express your feelings for the love of your life, then it is not just romantic. It is also the most thoughtful and passionate thing you can do for your significant other because it's always the little things that matter.
