In this crossover anime, I've been bound to two systems.

Silence began to spread through the room.

In the end, it was Kasumigaoka Utaha who looked away first. In front of Sawamura Eriri, she naturally took off her pajamas and put on her underwear.

Eriri Sawamura turned her head away from her, got up and went to the table, picked up a water glass, and took a small sip like a cat.

After finishing her water, she looked again at Kasumigaoka Utaha, who had taken off her pajama bottoms and was starting to put on pantyhose by the bedside.

"It's still early before school starts."

Finally, it was Eriri Sawamura who broke the silence.

"I just got up and changed my clothes; I wasn't thinking about going to school right now."

Kasumigaoka Utaha answered, already wearing her pantyhose.

She stood up, straightened her skirt, and went directly to Eriri Sawamura, taking the cup from her hand and placing it on the table.

"Hey, what do you want?"

Eriri Sawamura looked at her warily.

Kasumigaoka Utaha didn't answer, but suddenly raised her hand and landed heavily on Sawamura Eriri's bottom.

Besides the crisp "snap" sound, Eriri Sawamura also involuntarily let out a soft "Ugh—" moan.

"Huh?"

She emotionlessly mimicked the sounds the other person had just made, her eyes filled with mockery, and her expression turning to disdain.

"Your face is red. You actually have that masochistic fetish of liking pain."

Eriri Sawamura clutched her buttocks, her emotions running high.

"Who would have that kind of fetish! You're the pervert, aren't you? You clearly love it to death but always pretend to be unwilling, but when it comes down to it, you scream louder than anyone else!"

"Whose fault do you think this is? We agreed on fair competition so he could choose for himself, but he turned against us at the crucial moment!"

"Huh? You stinking woman, you actually dare to turn the tables on me? I'm not stupid, the pillows and bed in his bedroom smell like you! You're the one who broke the agreement first, aren't you! You're always thinking about running away, you stinking woman!"

"And what about the wedding? You actually accepted his proposal!"

"How could I possibly refuse! Ha! Now you're regretting it and being envious? Serves you right for being so awkward in the first place!"

"Envious of you? Envious of how you looked, blindfolded and handcuffed, unable to move on the bed like a sow! Do I need to describe your posture in detail?"

"What right do you have to talk to me like that? When I was pregnant with Qianyu, my belly was already so big, and I still clung to him every day, always looking like I was sexually unsatisfied. Who's the sow here?"

"That was due to an excess of progesterone in me. You had the same thing when you were pregnant!"

"At least I won't barge in and ruin things when others are halfway through!"

Kasumigaoka Utaha and Sawamura Eriri pressed their hands together as if wrestling, their foreheads touching, and their facial expressions gradually became frantic.

Chapter Seventy-Five: A Quietly Changing Relationship

The couple's heated argument traveled through the door and reached Mrs. Sawamura's ears as she was about to knock.

She slowly withdrew her right hand, covered her mouth with both hands, and her eyes were filled with uncontrollable terror.

A masochistic sow who enjoys pain?

Is this referring to Eriri?

Pregnancy? Excessive progesterone secretion?

Are you referring to that child, Xiao Shiyu?

Besides that, there are handcuffs and blindfolds, things like unsatisfied desires, forced entry midway... Most importantly, who is the "he" they're talking about?

These two kids haven't even graduated high school yet! What on earth are they talking about?!

Mrs. Sawamura usually considers herself a young person and has a very youthful mindset, but at this moment, she really feels that she is getting old and for the first time feels a sense of helplessness in not being able to keep up with her children's thinking.

She covered her mouth and slowly backed away. The shouts and commotion coming from inside the room didn't bring her back to her senses. She left her daughter's room door in a daze.

Inside the room, Kasumigaoka Utaha and Sawamura Eriri, panting heavily, collapsed onto the bed. After a three-countdown to their agreement, they simultaneously released their grip on each other's hands.

"Ugh! You damned woman, you pulled so much of my hair out!"

Eriri Sawamura, seeing the few conspicuous strands of golden hair on the pristine white sheets, couldn't contain her anger any longer and grabbed a pillow, rushing onto the bed once more.

"I was just about to say, do you even know how much my pantyhose cost? You've torn it like this!"

Kasumigaoka Utaha, not to be outdone, stretched out her hands to retaliate.

It was another bout of much noise but little action, just a lot of punches and kicks.

A moment later, Kasumigaoka Utaha rubbed her chest and curled up, while Sawamura Eriri covered her unnaturally red cheeks and rolled around on the bed in pain.

Inside Toyonosaki Academy, the two, known for their top-tier looks, are now completely out of sorts. If someone who knows them well saw them like this, they would be absolutely shocked and incredulous.

"Stop doing those pointless things..."

"As long as you don't provoke me..."

Eriri Sawamura stood up and watched Kasumigaoka Utaha take off her torn black pantyhose, her gaze silently shifting in another direction.

"How much is it? I can pay you back."

"Need not."

"Then at least I'll lend you mine."

"Your legs are too short, I can't wear them."

"Don't go too far! Why don't you just say it's because your legs are too thick!"

"Heh~ Give it to me."

Kasumigaoka Utaha smiled casually as she looked at Sawamura Eriri, who had instantly bristled again, and extended her hand.

"What, you don't mind that my legs are too short?"

Eriri Sawamura raised an eyebrow.

"It's barely usable, but it's better than going out with bare legs."

"Humph!"

Eriri Sawamura pulled a brand new pair of over-the-knee socks from her closet and handed them over.

She watched as Kasumigaoka Utaha put her socks back on, noticing the noticeable red marks on her thigh from where she had just scratched her—marks that weren't actually injured but were still quite visible.

"...Hey, does your leg still hurt? I have some liniment at home, I can get it for you if you need it."

After hesitating for a while, Eriri Sawamura ultimately couldn't bring herself to reveal her inner turmoil. Although she still acted with her characteristic tsundere attitude, she still managed to say it anyway.

In the dream, they spent their entire lives with someone. Although they didn't get along well on the surface until their deaths, humans are not plants or trees, and even flowers and plants should develop feelings after such a long time of living together.

Kasumigaoka Utaha's cold expression softened slightly after hearing those words. She got up and walked to the full-length mirror on the side, seemingly turning her body left and right to check the effect of the over-the-knee socks on her upper body, but in reality, she was turning her back to Sawamura Eriri to hide the unnatural blush on her face.

"It's nothing, it doesn't hurt much, it'll be fine in a while, no need for liniment."

"Oh."

"But you, I think my fingernail accidentally scratched your face just now."

"I dodged it; I didn't even get hit."

"Is that so? That's good."

"kindness……"

The two, who had just been at odds, suddenly found the atmosphere somewhat awkward after having the above conversation in this enclosed room.

"I'm going to brush my teeth."

"Oh, you know where the bathroom is... Oh right, the disposable toothbrushes are in the third drawer under the sink. Once you open it... Never mind, I'll go with you."

Eriri Sawamura led the way, and together with Utaha Kasumigaoka, they arrived at the washroom.

She took out a disposable toothbrush set for the other person.

After Kasumigaoka Utaha took the item, she stood to the left of the sink to wash up. Seeing that Sawamura Eriri was in a daze, she deliberately reached out and patted the empty space to her right.

Eriri Sawamura understood, took out her own toothbrush, and the two began brushing their teeth side by side.

The washbasin in the Sawamura family's house wasn't particularly large, and it would feel a bit cramped if the two of them used it side by side, shoulder to shoulder. But even so, they didn't seem uncomfortable or awkward at all; instead, they were quite harmonious and natural with each other.

In their dreams, their daily life shortly after marrying Suzumiya Chisato was often like this: the two of them would wake up together and wash up at the same time.

They didn't like having other people in the house, so they didn't have any servants.

So after washing up, one of them would prepare breakfast while the other would wake the two children up, help them change their clothes and make their beds.

Many similar experiences were vividly etched in their minds, subtly altering the relationship between the two.

"Mom seems to still be sleeping; she hasn't woken us up today."

"Don't bother Auntie anymore, let her continue to rest, have a quick breakfast and then go to school."

"Hmm...whether you come or not..."

"You come here. I'm not familiar with your kitchen, so I'll help you out."

"kindness."

The two went to the kitchen and divided the work reasonably.

Eriri took out a frying pan and started making thick tamagoyaki.

Kasumigaoka, on the other hand, puts toast spread with butter into the bread machine while heating the milk.

After Mrs. Sawamura calmed down a bit, she realized that she hadn't made breakfast yet, so she hurriedly pushed open the door to the living room, only to see steaming milk and sandwiches on the dining table.

There was a note on the table, left by her good daughter, saying that the two of them had gone to school, and also reminding her to reheat breakfast in the microwave if it got cold.

My daughter, who never lifts a finger in the kitchen, actually cooked? And the food was actually quite delicious?!

Mrs. Sawamura fell into a state of existential doubt for the second time today.

On their way to school, Eriri Sawamura and Utaha Kasumigaoka walk side by side.

Eriri gently nudged Kasumigaoka with her elbow.
