4 is for "happiness" and doesn't mean "to die"

Chapter 4

"So I'll just go on it?" Su asks, "It'll stay still?"

"Yup," Yui says.

Su gingerly swings one leg over the bicycle, which is kept still due to being on a stationary trainer. Su makes herself comfortable. The bicycle remains upright.

"See?" Yui says, smiling. She's adorably patient, with our interesting older sister.

I'm watching this scene unfold on Su's other side, as Yui is on the other, to give Su a sense of security in case Yui's bike does topple Su over. Su starts to pedal, and the bike really does remain stationary as only the back wheel turns.

A horrible noise screeches the air though. It's as if someone has turned on the vacuum cleaner.

Su stops pedalling. The noise also stops.

"Was that your bike, Yui?" Su and I ask at around the same time.

"Ah, that's the trainer," Yui explains. "It causes resistance so it feels like you're really riding on the road."

"Huh...." Su starts to pedal again, but stops after 16 seconds. I know because I was looking at the clock on the wall. I'm still looking at it. "Am I supposed to feel like I'm climbing a small hill?"

"Eh? Oh! I forgot to adjust the resistance level." Yui squats near the trainer and pats around the gadget for a bit. "Hmm ... it's not here. Let me get on, Su-chan. I'll fiddle with the settings."

Su and Yui exchange positions.

Yui pedals slowly, while adjusting with the gears on the handlebar. There is a click every time she changes the setting and soon I'm not looking at the chains that are attached to the pedal and back wheel.

Yui's butt is off the bicycle seat and her hips are swaying from side to side. I gape as I watch the mesmerising movements. She must be doing this purposely, mimicking her idol Ariana.

"That should do it," Yui mutters.

I peel my eyes off Yui as Yui gets off the bicycle, and I end up meeting Su's eyes. Su stares at me with repressed laughter and I burn.

Did she catch me gawking?

I hope she thinks I was just zoning out and I just happened to be looking at Yui's butt when I did.

Urgh. How embarrassing!

I feel like a creep.

I physically shake my head, ridding my thoughts and hopefully my negative emotions too.

"Ah, it's much better now!" Su exclaims. She's back on the bicycle, pedalling away, and Yui is back on the other side again. "Okay. I'm going to ride for 10 minutes just to get used to it. You two can go off and do something else. I'll be okay."

Yui immediately walks off but I linger, watching how stationary the bike is and how well the trainer is at holding it upright. I feel a soft hand against my elbow.

"C'mon. She'll be okay," Yui says. I glance back at Su. Su has gotten her earphones out and has plugged them into her ears. She's bopping her head to music I cannot hear. Satisfied that the bicycle won't topple over and injure Su, I follow Yui to the living room.

Yui's touch seems to linger even as she moves away to turn on the TV and casts to it YouTube video from her phone. She turns around and smiles at me. "Feel free to add a video to the queue."

I sit down on one of the comfy sofa seats and pull out my phone. Yui takes a similar sized seat.

As I go on the YouTube app, I'm wondering at the back of my mind on why I didn't take the 3 seater like I usually do. Perhaps because I want to distance myself from Yui for a bit.
