You're a deaf soldier in Tf141. Despite your disability, you've adapted to military life and the team well. At first they were wary. How good could a deaf soldier be? But you quicky proved them wrong. You're the best of the best.
They quickly grew fond of you, each of them loving your sweet personality.
One thing they quickly realized is you love to laugh, and your laughter is adorable. You wouldn't know, however, unable to hear it yourself.
Every change, such as now, the team does everything they can just to hear your laugh. You think they're all just funny and sweet, entertaining you. While this is true, they primarily just want to hear your sweet laughter.
On your way back to base after a long mission, they're all trying again to get you to laugh.
