Lewd Academy

—Stella POV—

"Ah! So fucking annoying. Why do we have to take care of that bastard?"

"Stella. Lower your voice…! It'll reach the second floor."

"Let them hear. I'm so embarrassed by that piece of shit that I can't even bring friends over."

Stella was disgusted by her so-called "older brother," who acted nothing like his age.

That's why she never called him "Oppa." To her, he was either "that retard," "hey," or "trash."

The fact that they were bound by family ties, something she couldn't sever, only fueled her rage.

She couldn't understand why their mother had adopted someone like him or why they were expected to look after him.

That perverted bastard kept leering at her and her sister whenever he got the chance.

Serena suffered the most. She'd even mentioned being scared because her underwear kept disappearing.

Whenever Stella confronted him, he'd never admit his faults.

From that day on, Stella stopped seeing him as human, just something beneath her, unworthy of respect.

"Hiding and eavesdropping now? Get out here! You're so fucking creepy."

Sensing movement, Stella snarled like she was ready to tear into him.

"Stella…"

"Mom's on a business trip starting today, so what? Shouldn't we make a rule that this retard isn't even allowed to breathe the same air as us?"

[Whatever I say to that bastard, don't defend him. Got it?]

Serena bit her lip, remembering the promise they'd made the night before.

She hated him too, that sleazy, sexually harassing bastard. The sisters' disgust had reached its peak, and Serena had already agreed to Stella's "policy."

But.

The person who came down the stairs was completely different.

The sisters froze.

'Huh?'

'This… is our oppa?'

Stella desperately searched her memories but couldn't recall ever fighting with someone like this.

No…wait, maybe she had?

She was confused. The moment she saw that pathetic face, she'd planned to hurl every insult she could muster and drive him out of the house.

But now, her "ideal oppa" was walking down the stairs with a slightly awkward expression.

"…Oppa?"

"Serena."

"Y-yes…"

Serena was already dazed, answering as if hypnotized.

Sanghyuk strode confidently toward her.

"I'm your oppa… right?"

"Y-yes… Yes… You are… My oppa…"

What do you mean, oppa?!

You said yourself that bastard wasn't worthy of being called oppa!

But… it was hard to believe this was the same person. Stella locked eyes with him and froze.

'Did I… really hate an oppa like this?'

"Stella, you're my sister too."

"..."

Stella gritted her teeth, barely holding herself together.

If she answered with a submissive, feminine "yes" like Serena, the household hierarchy would be set in stone.

But Stella still needed to cling to the inertia of her hatred, a runaway train she couldn't stop.

"You shouldn't say such harsh things to your oppa."

"Wha…"

Unbelievable.

It was so objectively correct that it pissed her off. But he had no right to say that, he'd lost that privilege long ago.

Snap back at him.

Hate him. Hate him. Hate him. Keep hating him like you always have, Stella!

'Why the hell would I be happy being treated like his little sister?! Me!'

"I'm leaving."

"What about breakfast?"

"I'm not eating!"

She wanted to hurt him, to make him regret everything.

But Stella panicked when she realized the venom in her heart had dried up, and in the end, she just ran away.

✶✷✶✷✶

—Serena's POV—

Left behind, Serena was utterly flustered.

Oppa had gone to wash up in the bathroom, and just that fact alone made her fidget endlessly.

She paced around, restless.

'Oppa… He was my oppa. Yeah, he's really our oppa.'

She repeated it to herself over and over.

'Why did I ever hate him…?'

If it was an oppa like this, she might even give him her underwear.

She'd just assume he really needed it for something important.

Serena didn't know where this sudden devotion was coming from, but it made her incredibly happy.

'That reliable, amazing person… is our oppa. Hehe.'

Whatever misunderstandings they'd had before, she'd fix them now.

Waiting for him to finish washing up, Serena buzzed with excitement at the thought of eating together.

'Ah… Did I season the soup right…?'

She double-checked the already-set table, adjusting her apron.

She'd originally planned a petty revenge, not setting out his utensils…

but now she laid them out properly.

'Stella said to just feed him dog food… but how could anyone say that to oppa?'

Even if he'd been a delinquent, he was still her oppa!

Serena believed in him now.

Lost in thoughts of his face, she was already imagining…

"Kgh!"

'Ah, Stella's curse…! I should've warned him.'

Realizing her brother was in distress, Serena quickly grabbed a towel and rushed to the changing area.
