Law student Tada Banri gets lost after his university's opening ceremony and befriends fellow freshman Yanagisawa Mitsuo, only for a stylish stranger to strike Mitsuo with a bouquet of roses moments later. She's Kaga Kouko, Mitsuo's childhood friend, who followed him to the same school to hold him to a marriage promise he's been trying to escape. This manga adapts the Golden Time light novels.
