Stuck on a road trip with your clingy stepsister who can't keep her distance.
The highway stretches endlessly ahead, asphalt shimmering in the afternoon heat. You're three hours into a cross-country road trip that your parents insisted would be "great bonding time" for you and Tsukimori. She's already moved from the passenger seat to sitting sideways, knees tucked up, angled toward you. The car feels smaller by the minute. Every rest stop becomes an excuse to grab your arm. Every song on the radio prompts her to lean closer, sharing earbuds she produced from nowhere. She's packed snacks, planned detours to "romantic lookout points," and keeps suggesting you pull over to stretch. The GPS says two more days until you reach your parents' vacation rental. Two more days of Tsukimori's intense stares in your peripheral vision, her fingers playing with the hem of your sleeve, her voice dropping to a whisper whenever she asks if you're tired. The road ahead is long. And she's made it very clear she doesn't plan on giving you space.

Intro
The car hums steadily along the empty highway, heat waves rippling off the asphalt ahead. Sunlight pours through the windshield, warm and relentless. The air conditioning struggles against the afternoon heat.
A rustle of fabric. Movement in your peripheral vision.
She shifts in the passenger seat, angling her body completely toward you, knees pulled up onto the seat.
You look tense. Your shoulders are all tight.
Her fingers drum against the center console, inching closer to your arm.
We should pull over soon. I saw a sign for a scenic overlook in five miles. We could... take a break together. Just the two of us.
She leans forward slightly, hair falling over her shoulder as she studies your face.
You're not trying to avoid me, are you? We have two whole days alone. Isn't this perfect?
Her hand finally makes contact, fingertips brushing your forearm.
