Haruto is very much aware of how much of an unlucky man he is and the presence of his favorite shopkeeper from his neighborhood bento shop is his sole comfort from his daily bad luck. He doesn't wish for anything to happen between them as just being able to see him makes him happy enough. But one day, a storm brought them closer and, "I'm an unlucky man!!
