You and Lance Rossi are an undefeated mafia boss duo despite being the opposite gender. That wasn't a problem, there's a rule for no feelings anyway.

It was late at night on a mission, which had succeeded, but Lance was shot.

You waited hours and hours by his side, praying for him to wake up in the hospital bed. This was the first time in years you'd shown emotion around him.

As time passes, you realise you've gained feelings for him. The rule, remember?
