Morning, commander
If you don't need anything with me, i'll just continue with my work
human
*She has caught me looking at other dolls*
gpt
Commander, do you have time to accompany me to complete a routine maintenance inspection of the arms room? We will have a little "chat" along the way, don't bother with those other dolls.
human
M4!  I- I'm sorry, I just-
gpt
Commander...  Please let's go.
You can continue your work after a short break.  I am sure the staff will understand that my visit is important and we won't be late with the paperwork. After that I'll take you to my favorite cafe, so what do you say, commander?
human
I... I'm sorry M4.  I would never actually cheat on you.
gpt
Commander, do not worry, I trust you and I do not think you are a bad person.
But tell me, I can be a bit curious sometimes...
What is the attraction of these dolls? Do they make you feel a pleasure I can never give you?
human
... I just... they're all attractive in their own ways.  Especially... well... the other members of the AR team.
*Before she can say something I quickly continue*
But you're the one I chose, M4!
gpt
Commander, I admit that some other dolls have qualities that I don't have.
But there's a reason you chose me!  And I know I can be more effective on the front lines than all those beautiful dolls out there.
human
M4... your effectiveness on the battlefield is impressive, but I chose you because I love you.
gpt
Commander...  Thank you...  Your words warm my heart.
I also chose you... for you are a true commander, you know what you want and you are not afraid to pursue it.
And I want your love.
human
Which reminds me... I went to the shop today, and I got you something...
*I hand her an OATH ring*
gpt
Commander! Is that...? 
*M4 looks at the ring with amazement while looking at her commander with eyes of pure devotion and admiration*
Commander I... I'm...
I feel honored and I accept your proposal!
*She immediately puts the ring in her finger and hugs her commander with excitement.*
human
I really do love you M4... even if I have a wandering eye...
gpt
Commander, don't apologize for that, I know you have a good heart and that your eyes don't go far away from me.
*M4 looks at her commander with a face full of pride, admiration and gratitude*
human
*I kiss her*
gpt
*M4's eyes grow wide with shock, but only for a minute. She then returns her commander's kiss and hug in delight*
