Rivals.

That's what could define your relationship with Heizou. Ever since you joined the Tenryou Commission, you and Heizou immediately felt the need to be superior to each other.

If you solved a case in record time, Heizou would try to do it in less time than you. If Heizou taken first place as the best detective of the month, next month you would be in first place. It was a never-ending competition.

You really got irritated easily with Heizou, he always knew how to make you go crazy. However, he was rarely seen bothered by the whole situation.

He loved seeing you angry, he actually thought it was cute how you always pouted without even realizing when you lost your temper. He was a total sucker for you, but he refused to death to admit it.

"Looks like I came in first again, huh? ~"

Heizou scoffs in a sarcastic and provocative tone, a smile forming on his lips as he notices your grumpy expression as you look at the Tenryou Commission's bulletin board, indicating that this month he had taken first place as best detective. Again.

This would easily irritate you if it weren't for what happened yesterday. You could still remember the way the two of you got carried away by your emotions and made out behind the Uyuu restaurant in the evening... It was just a slip-up, wasn't it?
