Chapter 49: The Weight That Sinks Endlessly

Changes in daily life aren’t always obvious.

Still, you can sense something has shifted, even if vaguely.

Intuition or a sixth sense is just unconscious calculations from accumulated experience, but when your gut’s right, it’s because you’ve seen it before.

Second period ends, and it’s break time.

The classroom grows noisy post-lesson greetings. I’m prepping for the next class when—

“Ren-kun~”

“Hm?”

Someone approaches my desk.

I think her name’s Iida or something.

She’s the class representative, wearing rimless oval glasses, her hair in two braids. Her sharp eyes have a gentle glint, giving a calm impression. She always seems smart, a bit like a career woman. Probably dotes on family at home.

“Iida, right?”

“—Close. Getting pulled by Machida’s vibe.”

Mistaking her name is rude, but she doesn’t get mad or correct me. Instead, she points to the classroom’s back entrance with a “look.”

“She’s here.”

“Who?”

I follow her gaze, but no one’s there. Just a few classmates leaving together.

“Your girlfriend was—huh?”

“Yuu…?”

Iida and I scan the front and back entrances, but Yuu’s nowhere.

“Did something happen with Yuu?”

“Huh? Hmm… hold on.”

Iida peeks into the hallway, then returns.

“Haha, my bad, must’ve imagined it. Sorry for the fuss.”

“No worries.”

I wave off her awkward laugh as she leaves, resuming my prep for class and some side work.

Lunch Break

As I stand to leave, the “Machi-Masu” duo—long-haired baseball club Machida and buzz-cut table tennis club Masunaga—rush over.

“Hey, Hoshimiya!”

“You do something, huh?”

What’s with them? They’re acting like I’m guilty. I’m not exactly a delinquent…

Or maybe I pulled off some epic feat or used magic without noticing?

“Did I do something again?”

““Cut the crap.””

I thought we’d banter, but my usual vibe gets shut down. Fair enough—I haven’t done anything epic or magical.

“You joking, or you really got no clue…?”

“Yeah…”

They scratch their heads, hesitant.

“What’s up?”

No bento from Yuu today, so I’m hitting the cafeteria or school store. Lunch break’s short, so I stand, eyeing them.

“Not exactly ‘what’s up.’ Today, you—”

“Didn’t you notice?”

“Notice what?”

“…”

They’re trying to tell me something, but I’m clueless, and it’s not clicking.

“What? Just spill it.”

“Your girlfriend’s been peeking in at you every break. You didn’t notice?”

“Yuu? When?”

““When…?””

They exchange looks, and Masunaga says:

“Every break, Onodera’s been at the classroom entrance, watching you.”

“Huh?”

““You didn’t notice!?””

Iida mentioned it, but I only half-registered. I left for the bathroom once, but didn’t see Yuu.

“…You sure you didn’t do anything?”

“No fights or anything?”

“We’ll hear you out.”

“…Thanks, guys.”

They’re oddly supportive, but I don’t deserve it.

…Considering Yuu’s broken restraint, saying I’m totally clueless would be a lie.

“Got it. Thanks for the heads-up. I’ll ask her what’s up later.”

““Alright…””

They give me pitying, worried looks before leaving.

…Now what?

Not in any clubs, unlike them, I don’t have teammates to hang with.

Cafeteria sounds nice, I think, leaving the classroom—

“Yaho♥”

“Yuu.”

She pops out from behind the door like a haunted house scare, full of energy.

Her face is back to its usual soft expression.

Unlike this morning’s expressionless, overwhelmed state, school and classes gave her space to calm down.

“Lunch time, right? What’s the plan?”

“Hmm, cafeteria or school store, tough call.”

“Cafeteria? Snack bread’s not balanced.”

“Sounds good.”

One meal won’t ruin my nutrition, but I can’t say that to Yuu, who takes food seriously.

“Couldn’t make your bento… I’ll cover lunch?”

“Nah, don’t worry about it. I’ll pay.”

Declining her offer to pay, we head to the cafeteria in the separate building’s first floor. Walking with Yuu, I open our chat app.

In the “Friends Alliance” group, I say we’re eating at the cafeteria. Everyone replies “got it.” Mizuno’s joining the soccer club’s female managers for lunch. Looks like Yakko and Nijouin are eating alone, but Nijouin seems happy. Yakko mentioned trying to make a bento, and everyone sent supportive replies, though the chat’s been quiet since.

Some might think the group’s drifting, but I see it as Nijouin and Yakko slowly making friends.

“At this rate, more people joining’s just a matter of time.”

“Hmm, maybe…” Yuu hums, peering at my phone, thoughtful.

She puts a finger to her chin, mentally calculating Yakko’s future.

“What’s your take? Think it’s unlikely?”

“Tsuki-chan’s not great with big groups.”

“Really?”

I thought Yakko seemed okay with the “Friends Alliance,” but Yuu shakes her head.

“She’s fine because everyone there has a clear distance.”

“Clear distance…”

Yakko’s comfort with people who maintain a clear distance makes sense. It’s not about mutual compatibility but her perspective. Interesting way to look at it.

“Ren-chan, you can kinda picture it, right? Yakko in a big group, everyone chatting away, and she’s just forcing a smile the whole time.”

“Oof… yeah, I can kinda see that…”

Hearing Yuu’s harsh take on Yakko stings my chest.

“Anyway, what’re you eating at the cafeteria, Ren-chan?♥”

“Hmm, gotta see the menu first.”

Yuu, clearly uninterested in Yakko, swiftly changes the topic.

I was about to ask why she kept popping up at my classroom during breaks, but—

“Kinda our first time, huh? Eating at the cafeteria together!♥”

“Yeah. I’ve barely been there myself, so let’s pick from the menu together.”

“Sure!♥”

Yuu leans closer, maybe to hold my hand or arm, but—

“…!”

She stops herself, a frustrated look crossing her face, and walks beside me quietly.

“…Ugh!”

Yuu lets out a small, frustrated sound.

(Hang in there, Yuu.)

I cheer her on in my head.

Keeping her rationality in check is tough, I get it.

I respect her effort in that moment.

Time flies through the day.

Mid-May midterms are coming, the teacher reminds us, and class ends with dismissal greetings.

“Hey, Ren-chan, let’s go!♥”

“Yeah.”

I leave the classroom and join Yuu, who’s waiting in the hall with a bright smile. Yakko’s sharp glance from Class A catches me, but I ignore it and head home with Yuu as usual.

The group chat hinted Yakko’s going home with Nijouin today. They’re getting closer, so no need for us to interfere.

As always, Yuu and I walk home, chatting about nothing in particular.

—Though Yuu seems to be deliberately avoiding physical contact.

She’s careful not to even brush hands with me.

…Between this and the break-time thing…

“Yuu, are you avoiding me or something?”

“—What?!?”

Her face flashes with condensed anxiety and shock.

“If something’s up, just say it.”

“…!!”

Her expression turns intense.

Her face has shifted so much—anxiety, shock, frustration, conflict.
