Golden Time, Vol 4

Tada Banri is starting with his ambitious journey. As luck would have it, during the opening ceremony for the freshman class, he happens across an unfortunate person from his past. Her name is Kaga Kouko, a buxom-beauty who slaps Banri's new friend, Mitsuo, across the face with a bouquet of roses. Just who is she and what's her beef with Mitsuo.
