Armin's DID surprise

so this is the result of me killing 2 birds with 1 stone. I wanted to give Karen and Armin school uniforms (they're at a college level, but in the story it's a space age theme so I'll explain the uniforms later) and do a DID since I hadn't done one in so long. so enjoy. still working out the details, but the story will have them in a type of university, while being fighters (they use melee, ranged and even ships of some types, along with their unique powers) as well.

also, here's a little back-story: Armin is your typical 'cool guy' main character, and he even wears his uniform in different ways than others to be 'cool' and maybe a bit of defiance mixed in. he likes doing things his way which often results in clashing with the plans of his instructors and commanders, but his knack for getting the job done even so grants him a rank to his own because of his skill. Karen has been Armin's girlfriend since they were young and been a close friend since childhood, she's brilliant, pretty and talented, as well as a loyal observer of the rules and protocol (usually) which sometimes gets her into arguments with Armin, and sometimes also saves him from deeper trouble as well.

as for what happened in the pic: Armin came back to their apartment one night after having been followed by some strangers, only to find the most important person in his life tightly bound and gagged with tape, at first he just stared, but once Karen's muffled noises got more insistent, he rushed over and freed her.

oh also, just in case anyone was wondering, they are in their 20's. and I know there's a lot of sloppiness and lackluster stuff in this pic, but I'm just surprised I even managed to draw out that much detail, though I still think it's pretty sucky. (definitely not ready for criticism yet.) but I hope you all enjoy it.

as one last thing: what would you do if you were Armin?
1) come into the apartment and close the auto-door, and stare at her (caution, may result in consequences)
2) come into the apartment and close the auto-do or, and take pictures! (definitely will result in painful consequences)
3) come into the apartment and close the auto-door, and rush to free her, but remove only her gag first, to have a little discussion, maybe a kiss, anything to delay... bwahaha
4) come into the apartment and close the auto-door, rush to free her and receive a hug and kiss of gratitude, and then find out what happened.
5) other (please specify)
