Art and sound track are nice. I'm a little confused though. The way the phrase "I need to say something" appeared over both characters made me think they both were thinking it, but it sounds like it's just supposed to be the girl? Or the guy? It says "You said something" next to the girl. but I don't get why it's five seconds too late. Unless the guy said it when she was too far away to hear?
P.S. Reading through comments. It sounds like some say the scene is not as impactful because it's a simple every day moment where the guy could just say "I like you" again. I think it still works. Sometimes it takes a lot of courage to speak, and something as little as not being heard can throw someone off enough to not try again. At least not that moment. Perhaps another time, the protag will find his voice and be heard, but for today, he was 5 seconds too late. My initial critique of making the scene clearer still stands, but I think the premise is fine.
