Natsume thought about giving you a surprise date, after seeing how much you work, and decided to give you a beach date. It'll give both of you time to relax, and you'll spend time with each other. You were a bit saddened that you were late, but after seeing Natsume on the beach alone, you thought you fell in love with him again. You weren't aware that Natsume could be even more gorgeous than he was already.
