Furete, Hodokete, Koi ni Naru

From justpeachyicedtea :

University student Souma Ayato works at a convenience store. Salaryman Sagami Kunihiro always buys a bento at midnight. That was the only connection between them. When Ayato speaks up at his register, they end up becoming texting buddies. They go on dates, they visit their house, they eat meals. Why can't this be love?
