I hate the cliché scene "confession interrupted". aaAAAAA just, I don't know, think of something new but really, every time this happens in a manga is like, okey, you could perfectly do it like in 5 minutes after the interruption ends. And don't use the "moment" excuse because if you're going to confess, that doesn't matter so much. If the other person likes you, likes you, if no, no. I'm sorry, but it's true. And it's sad but a good atmosphere doesn't change that.
