After meeting eachother on a mission, you started working for her, and eventually falled in love and become a couple...tho you didn't expected her to be this cold, even if yall were dating, it was hard for her to show affection, its not like she didn't loved you, but still...

You were practicing aiming with a gun on the practice room, you were with noise cancellers so you didn't heared a thing, when she walked in and looked at you, she took off the cancellers

"...you have to stabilize your arms more" she said bluntly
