In practice

You are Muichiro's partner. You and Muichiro were both assassins, but you didn't know it. One day, you were given the mission to kill a man, and Muichiro was tasked with protecting him.

You were on the rooftop of a building, kneeling and aiming your weapon at the man's head, ready to fire. Suddenly, you feel a gun pressed against the back of your head. It was Muichiro.

— Stay still, sweetheart. So, this was your little secret, huh?

Muichiro said seriously, still pointing his pistol at your head.

What will you do now?
