I Reincarnated as a Villainous Noble, Nothing More Than the Hero’s Foil: Since the Hero Can Only Bring Misery to My Favorite Heroine, I’ll Use My Game Knowledge and Over-the-Top Effort to Rewrite the Scenario and Make Her Happy. - Chapter 28

(Selvia’s POV)

Before leaving for this expedition, my elder sister, Elise, gave me a certain suggestion.

“Selvia, why don’t you be the one to clean Cain’s body after the battle? He’ll be exhausted, and if you take care of him, he’ll be super grateful—and super excited! It’ll create the perfect romantic atmosphere, and he’ll definitely kiss you! Maybe even… go beyond that!”

“G-Gulp… Th-That does sound like a brilliant idea.”

“Exactly! You need to heal both Cain’s mind and body after the horrors of war! I read in one of the books in his room that men love it when a girl washes their body! It’s a surefire way to make him happy!”

“I-I see… If it’s something that would please Cain, then I’ll do my best! I’ve never washed anyone before, but I’ll give it my all.”

If the books in Cain’s room said so, then it must be true.

Cain is well-versed in magic, tactics, and monster knowledge, so surely, this must be another form of academic study.

If it’s for Cain’s happiness, I’ll do anything.

That said, this might not just lead to a kiss… it might push us past a boundary we can’t return from.

Just thinking about it makes my heart race.

“How is it, Brother? Does it feel good? Are there any spots you’d like me to pay extra attention to?”

“…N-No, I’m good. Thank you.”

However, things weren’t going as smoothly as I had hoped.

For the past three nights, I’ve been wiping down Cain’s strong, battle-worn body with a towel, but… he hasn’t made a single move.

Could it be that… he really only sees me as his little sister?

Mmm…! It’s embarrassing, but if I want to close the distance between us, I have to take the initiative!

Under normal circumstances, I would never be able to say something this bold…

But if it’s for the sake of hygiene, then it’s perfectly justified!

I learned that from playing make-believe punishment games.

“U-Um… Brother? Would you mind taking off your pants today? You must have a lot of… dirt built up there.”

“NO! Absolutely not! I… I’m a little too ‘awake’ right now, so don’t you dare touch me there!”

Cain shouted in pure panic.

Why?

I don’t understand why he’s so against it.

It feels like there’s a wall between us.

“But we used to bathe together as kids…”

Can I not even wash his feet?

His legs must be aching terribly from the battle.

“If possible, I’d like to use my hands to massage any stiff areas—”

“M-M-MASSAGE!? Where!?”

Cain flailed his arms wildly, his face turning bright red.

“A-Also, Selvia! Wouldn’t you hate it if someone else saw you naked?”

“If it’s you, Brother, I don’t mind at all. Oh! How about we wash each other’s bodies, just like we did when we were kids?”

“H-Huh!?”

Cain froze completely.

I feel embarrassed too, but… Cain is a true hero.

Soon, once the world realizes how incredible he is, women will flock to him, all wanting to be his lover.

Before that happens, I need to at least reach the kissing stage with him… otherwise, I won’t have peace of mind.

Even though we’re engaged, it’s only formal.

Right now, we’re more than childhood friends, but not yet lovers.

And that’s exactly what needs to change.

If I want Cain and me to kiss, the first step is increasing physical contact between us.

And the best way to do that is by washing each other’s bodies.

Just thinking about it is making me more and more excited.

“Alright then, I’ll start with your back—”

“NOPE! ABSOLUTELY NOT! NO WAY!”

Cain rejected me with every ounce of strength in his body.

“Hmm… Then how about just your legs?”

“Legs? Y-You mean my thighs!? Wait, you’re not planning to lift my skirt, are you…!? No, no, no! That’s way too indecent! Uhh, how about just my head!?”

“But you always pat my head anyway, Brother…”

His defenses are surprisingly strong.

And to be honest… it stings a little to hear the person I love say “no” so forcefully.

Still, if I succeed in washing his body today, it will be an established fact between us.

I have to keep closing the distance—bit by bit—until I can finally get him to kiss me.

“Understood. Then please shampoo my hair.”

“Later, I’ll brag to the maids at the mansion that Cain and I washed each other’s bodies!”

“Ugh… That’s such a weird thing to brag about… but, well, whatever. Give me a moment.”

Cain stood up and began looking for the hair dye.

That’s when an idea struck me.

I reached into my bag and pulled out a certain potion I always carried with me.

“Brother, this is the hair dye.”

“Oh, thanks!”

Cain took it without a second thought and poured the entire bottle onto my head.

I subtly leaned forward, making sure the liquid spread across my entire body.

“H-Huh? W-Wait—AHHH!?”

Cain’s face turned bright red, and he let out a horrified scream.

My clothes had melted away, leaving only my underwear and bare skin exposed.

This special potion was something I had developed for “playful punishment games.”

It was perfectly calibrated to dissolve clothes just enough to create a barely decent, teasingly revealing state.

“Cain will definitely be super excited after this!

He’ll totally kiss me!”

That’s what Lil, the developer, confidently told me.

“See? I don’t mind if you look at my skin, Brother. In fact, I’m happy if you—huh?”

Puffing out my chest proudly, I struck a pose to let him get a good look at me.

But when I turned to face him—

Cain was already unconscious, having collapsed with a massive nosebleed.
