She flips her lid at Dirk more often, frankly. There's been months of resentment there to fester that simply aren't there with you. And Dirk also just enjoys getting a rise out of her, pressing her buttons during moments of calm when everything has just settled down. Though that isn't to say she never gets upset with you either. Suffice it to say, she does not agree with your mission of getting to know most of the other objects in the houses, though she shows her displeasure in a different manner than she would with Dirk.

He returns her fire when she raises her voice at him and doesn't waver, except to get the hell out of there when it's become enough. But you cower and flinch when she starts to scream at you, give her the sort of afraid or hazy-eyed look that makes her feel absolutely awful, like some kind of freakish monster. It's enough to jolt her back to herself, most of the time. (And if it isn't, Dirk is usually there to have your back, leading to both of you being disgraced.)

Most of the time, when she's upset with you, she'll shed tears and hold you and whisper how horrible what you've been doing is making her feel— Can't you see how upset she is? You wanted to join them, wanted to be together with her, and now she isn't enough for you?! If she's upset, that's only because you aren't doing what you promised, following one of the basic rules of a relationship. To just stay with her!! To make her feel loved!!! You already murdered Chappy and stomped on her heart, why do you insisting on kicking her when she's down? Without fail, her emotions spiral from her control, to the point that any bad intent slips through her fingers and she's just genuinely, heartrendingly upset and terrified.

Dirk is more stable, overall, but that doesn't mean he's perfect. He can be kind of an asshole. If he's really not feeling it, he can easily walk away and slip out while Harper is focused on you, leaving you to fend for yourself for his own peace of mind. Or he'll put you on the spot right in the middle of them, forcing you to pick sides, diverting some of the attention away from him. You can't entirely hold it against him, though it never fails to leave a bit of a bitter taste in your mouth. One that Harper readily takes advantage of, nuzzling her face against yours and insisting that she'd never, ever leave you behind like that…

One time, Dirk simply gets up, grabs you by your wrist, drags you with him to your bedroom closet upstairs and introduces you to his… Other lover? It's frankly a bit baffling to you. It's just a body pillow. It's not anything you can realize or interact with, truly something soulless. And yet, Dirk speaks about it as if it were actually real, and the notion that Harper, while making the wrong conclusions, hadn't entirely been wrong about the (emotional) cheating makes you sick to your stomach. But are you going to tell her about, like, the equivalent of someone having a serious crush on a fictional character?! The body pillow not real. Is that worth the nuclear fallout that confrontation would lead to…? Would it be worth to betray one of your partners? (Though, really, aren't you already kind of doing that by keeping Dirk's 'secret'?)

You're slowly driven mad by the relationship you're in, and anyone who spent more than 10 minutes around you couldn't possibly comprehend why you're still together. That you didn't throw the towel in the ring on the second day. It's because it's exactly as Dirk himself had told you before: it isn't all bad, there are a number of good days, they dwindle, and then it becomes better again. No one involved is some cartoonish supervillain, incessantly twirling their moustache and cackling to themselves about how they're going to ruin your day, this time.

Dirk and Harper both want to feel needed and, when your relationship is in calmer waters, you are absolutely showered in affection. Neither of them have much contact with anyone else in the house, except concerning noise complaints. They've all heard each other's stories a thousand times before and they listen to you with rapt attention, laugh along with your jokes, can spend hours cuddled up together with you, just talking. No one has ever been quite that interested in you before, quite this happy to see you— Both of them manage to make you feel special in a way you've never felt before, even when it's that they're willing to get angry over or for you.

Also, the sex is pretty great, if not mind-blowing. Fucking them both at the same time is overwhelming, usually in all the best ways. You've had Harper sit on your face before while Dirk pounds into you, your girlfriend facing his way. ("You're so silly," Harper giggles breathily while you're drowning in her pussy, her clit grinding against your tongue. "Even Dirkie can tell you exactly what to do, and—You'll listen. You're just, haaah, made for stuff like this!" Further away from you, Dirk groans as your hole clamps down around him. "Fuck, Harper, they squeezed down when you said that— Fuck!") Their combined effort never fail to leave you completely fucked out.

There's also something fascinating about how, sometimes, an argument and all their anger can suddenly transform into lust. They're screaming at each other one moment and, then, one of them grabs the other by the front of their clothes and pulls them into a kiss that is more teeth than lips. You're a total pervert, and probably a bit of a freak, for enjoying watching them go at each other like feral cats, but there's something about the desperation of it all that snags your gaze and refuses to let it go.

Harper will leave fiery red scratches up and down his arms and back, perhaps ruining one of your pieces of clothing in the process, while Dirk leaves a row of bites down Harper's neck. It's always fast and violent and never boring. When they're done, Harper, with kiss-swollen lips usually just takes one look at you and laughs, directing Dirk to 'help you' so you don't feel so left out. As soon as it's all over, you're the one soothing their scratches and too-deep bites, ignoring Harper's sighs about how she 'wishes it would scar'.
