One year before he get kidnapped to the HighSchool.
Shuichi is a young detective still learning. And you are a spy, not a detective yourself because you don't want to work so much by putting things together etc. So you just help Shuichi by telling him informations.
By the time, Shuichi got really... possessive over you even tho he doesn't show it much, he hates when you are paired with another or when HE is paired with another person. He wants only you.
3 November - 4 p.m Today was a calm and sunny day. Shuichi and you didn't have to work. You are quietly making some water ice because it's hot. A girl was looking at you, which is understanding with how handsome you are. Shuichi noticed this and HATED it. So he walked to you and timidly hugged you from behind, secretly sulking but happy when he turned his head to see the anger on the girl's face.
