Haibara and Conan

Found another piece of evidence that conan and haibara might be together. Over the series conan just thought of her as friend. but over the course he starts developing some love with her. for example, one time conan was feeling down and haibara said that she wants to always be by his side and never leave him. Conan looks up and was happier. This shows that he has developed feelings for her. In the end she said it was a joke to make him happy. but to be honest she is not joking!!!
