Hokuto's Past - S1.E6

Chiwa thanks Misaki for arranging the party, but Misaki says she did it for Hokuto, not her. Chiwa is now the corporate marketer at Yamaguchi. Chiwa accidentally sees an article about Hokuto and Misaki's relationship and is shocked to find they had been dating. She confronts Hokuto, but all he says is, "that was in the past. I only consider her a business partner now, nothing more".
