Sometimes the right train leads you back to the one who’s been waiting all along. When ordinary high schooler Ryou saves a girl from a groper on the train, he doesn’t expect her to be Hina, his childhood friend he’d drifted apart from years ago. What begins as an awkward reunion quickly turns into a sweet, everyday romance as the two navigate school life, rediscover their bond, and realize that fate might have given them a second chance. Lighthearted and warm, this rom-com is filled with gentle humor, blush-worthy moments, and the charm of first love rekindled.
