Akai Shuichi X OC: Tame the tiger

Guess who's the tiger. It doesn't matter right? The only matter is that you tame the tiger, and then afterwards you can do whatever you want to the raging tiger.

The story of Akai Shuuichi is similar to Hera Phantomhive, the Black Organization killed her both parents that loves her so much. That day she trained and trained until she found out that her uncle is the Boss of FBI, she told him that she needs to destroy the Black Organization. And her uncle told her no. It will risk her life, but Hera is really stubborn. She convinced him over and over again until he gave the permission to Hera.

But in ONE condition, Akai Shuuichi who's in the Black Organization right now will monitor her. If the members of the organization found out she's a rat, Akai Shuuichi will bring her back in the hands of FBI.

What if while monitoring her Akai Shuuichi grow something inside him.
