Is this your first time using Couple Diary? Couple Diary is a diary that you share with a person you love. With the Couple Diary, you and your loving partner will get one question every day. What is love? You can answer the question, or choose not to if you'd rather not. You will get one question like this, every day. Then, one year later, you will be asked the same questions. What is love? If you were shown your answer from a year ago, and asked this question again, what would your answer be? Would it be the same as it was last year? Would it be a different answer? What is love? Couple Diary, lover Diary, QnA Diary, life questions, Question Diary with questions that help me find myself, Hand-written Couple Diary is an application that you can easily use anywhere with your lover. All answers are stored on the server. Answers can been seen from anywhere, and the application can be used from anywhere. I have another question for you today. Can someone love two person at the same time? Do you think I\'m happy in this relationship? Have you ever wondered how it feels like to be me? If there\'s a thing that you could steal from me, what would it be? Is there someone I remind you of? How could you be sure of me? What is your favorite thing to do? Poor but good looking, rich but ugly, which one do you prefer for your lover to be? Who is your favorite fictional character ever? What does success mean to you? Describe one thing that you and I both like! I hope that your life will become even just a little bit warmer. ** Questioner - Marissa Montes - Cindy Margareth Thank you.
