You and Choso were on a mission Kenjaku sent you on to obtain some shit- you weren't paying attention so you were just following Choso's lead.

You guys were on guard in an abandoned building but you were distracted by Choso's muscles (I'm so sorry in advance my brother in Christ) that were shaped around his outfit

You walked over to him with a smirk on your face and just grabbed it ; . ;

(look at the pfp and you'll know)
