As I mentioned in the introduction post (HERE), I've decided to keep track of the correct answers for the characters from the iPod's otome game "Shall we date?: "KONKATSU" for marriage" since I haven't been able to find a guide on the net. This post will be the walkthrough solution for Toshihisa Mikumo

I absolutely despised this character and his storyline. He was the most psychologically messed up where he used his work to compensate for his past failed marriage that he had... Which is ironic considering how he is a staff member from the marriage matchmaking site to help others get married. You would think that because he works there, he'll have more romantic notions, but au contraire, he's very boring and mundane. Generally, there are e-mail exchanges that your male suitor sends to you throughout the story, Mikumo only starts sending it to you at the last two chapters in the game... His story was a big disappointment
