Stoic Ochi Bodyguard

Does your ochi bodyguard really need to folllw you everywhere?
Sleep in the same single person bed as you?
Follow you into the bath?
Prepare every meal?

>ask your ochi to give you a little space, since you're pretty sure you're never in any actual real danger
>her face looks pained for a split second, before she returns to her normal blank expression
>"Of course, my lord. As you wish."
>finally get to sleep in private, door closed, room and bed all to yourself, just like the old days
>except everything is different
>somehow now you can't get comfortable, you're always too hot or too cold (normally her undead body with its strange temperature behavior warms you up on cool nights and cools you off on warm nights, but now you're on your own)
>you can't tell where to out your arms anymore, usually they're hugging her softness like a giant overstuffed teddy bear
>decide to get a glass of water to calm yourself, but in the blink of an eye it's wobbling on your nightstand. Plus, the door is now slightly ajar.
>she's only that sloppy when she's very distressed
>next morning, you take it back and say she can be as close as she wants
>barely reacts as usual, only gives a subtle nod and an "Understood, my lord."
>but as you turn away, out of the corner of your eye, you swear you can almost see a relieved sigh and a slight smile

Big, tough stoic monsters are the best. I want try and fluster them to see how they react.

>decide you're going to fluster your ochi bodyguard because nobody's tried assassinating you in the past...ever, actually
>give her a frilly maid outfit to wear, saying it'll be better for blending in with high society than her tattered samurai robes
>she blinks at the outfit twice, turns to face you, gives you a flat "I see," and wears the dress (complete with cat-ear headband) during her afternoon sword practice without further reaction
>try sneaking up on her, to catch her off guard and tickle her
>every time you try, she turns again to face you, utterly baffled. One time, you go for broke and tickle her anyway. After a few seconds of her trying to figure out why you're doing this, she puts two and two together and makes a strange noise that (kind of) approximates laughter, both very earnest and totally unconvincing
>eventually she confronts you, bowing deeply
>"My lord, I hope I am not speaking out of turn, but your recent behavior concerns me. Has something upset you? If so please simply inform me, if it is in my power to fix I am open to your correction."
>"Oh no, nothing like that," you shrug. "I was just checking to see if I could fluster you a little, but you're surprisingly stoic."
>"I see. I apologize for the disappointment."
>"No, not at all. It's a good thing, actually. If nothing fazes you, then if something ever really happens I can 100% trust you to keep your cool and keep me safe."
>"I-Is that so..."
>"Yeah! You're the best bodyguard ever."
>normally she formally excuses herself when leaving your presence, but this time she just hurridly nods and awkwardly power-walks away from you, turning the first corner she can
>once she's out of your sight, she covers the happy grin that's taken over her deeply blushing face with her hand, shakes her head for a second to regain her composure, and manages to return her face to normal after a few minutes
>too bad for her, her reflection was visible in the flat screen TV the entire time
