The Hayase siblings decided to indulge in the cake for breakfast, with Haruka more eager than Haruto—the birthday boy himself.
She had a notorious sweet tooth, and dessert always seemed to have its own designated space in her stomach, separate from regular meals.
Chiyo was still busy in the kitchen, quietly preparing breakfast for them as usual.
Though she had been their stepmother for years, the siblings still considered her somewhat of a stranger, so she kept her distance from their moments together.
Meanwhile, their father, Akihito, lay passed out on the couch, still drunk from the previous night.
Haruto, taking charge, sliced the cake and served the best, largest piece to his sister, placing it on her plate with a smile.
"Brother! I told you, let me serve it! You're the birthday boy. Ah, you're a man now!" Haruka chuckled, teasing him.
"You're supposed to be the one eating first and getting the biggest slice!"
"It's fine, Haruka. You go ahead. I know strawberry shortcake is your favorite. That's probably why you picked this cake for me, right?" His smirk deepened as he playfully called her out.
Caught red-handed, Haruka's face flushed with embarrassment. Without a word, she dug into the cake, taking a big bite.
Her cheeks puffed out with the cake like a hamster hoarding food, and her mouth was covered in whipped cream.
"No! It's not like that!" she tried to protest, her voice muffled as she chewed, making the scene all the more adorable.
Haruto couldn't help but laugh at the sight of his sister. She looked so innocent, so unguarded—so different from the cold, distant Haruka he remembered from the future.
After their mother's death, their birthdays had become awkward, silent affairs, full of tension and grief.
But now, things were different. He had broken the ice earlier by barging into her room, and maybe that had given her the courage to open up as well.
Smiling warmly, Haruto leaned forward and wiped some frosting from the corner of her mouth with his finger.
Without thinking, he licked it off, causing his sister's eyes to widen in shock.
"Eat slowly, Haruka. You can have as many slices as you want," he reassured her.
Haruka, still flustered from the gesture, tried to respond, but ended up choking on her mouthful of cake.
She coughed violently, hitting her chest in a panic. In an instant, Haruto grabbed the jug of water, poured her a glass, and handed it to her with swift precision.
"Here, drink this," he said, his voice filled with concern.
As she gulped down the water, he stood up and gently rubbed her back, helping her calm down.
"I told you to be careful," he scolded softly, relief washing over him.
Haruka nodded, too busy recovering to respond, as she kept sipping the water.
"Is she alright?"
Chiyo's worried voice cut through the moment. She had paused her cooking to glance over at them.
"She's fine," He replied, glancing at Chiyo.
Her worried expression softened into relief before she turned back to the stove, continuing with breakfast.
Haruto's eyes lingered on her for a moment, watching the way her big buttocks swayed as she moved.
The tight blue shorts she wore only accentuated her curves. It was odd to him—seeing her libido so high on the system.
'Is it because Father doesn't touch her… or is she secretly a pervert?' he thought, his brows furrowing slightly.
Almost as if the system was reading his thoughts, a familiar chime echoed in his mind, and the translucent screen appeared before his eyes once again:
[Ding!]
[New Quest Available!]
[Quest: Lonely Married Woman - Part I]
[Description: Chiyo Hayase has been neglected by her husband. She yearns for touch and affection, leaving her in a state of desperation.]

[Rewards: 150 EXP, 5000 Sex Coins, New Skill: Alluring Whisper, Item: Pocket Pussy.]
[Time Limit: Until breakfast is finished.]
Haruto took a long, deep breath and let out a sigh, so loud that even his sister, already seated at the dining table, noticed.
He knew from the novels he read that a system like this was meant to be a tool to help him achieve his goals, but why was it so focused on something so sexual?
'Does this mean I need to seduce my enemies' women, mothers, sisters, to destroy their lives?'
A grin slowly spread across his face. 'That must be it.'
Daiki had taken away his sister and made her life miserable. Maybe Haruto needed to do the same to him and steal all the women he cared about.
The system didn't seem to mean him any harm—it only seemed to offer him power over women.
And who, in their right mind, would reject a system that could fulfill 95% of men's wildest dreams?
His father, still groggy and hungover, had just slumped in front of the television behind the dining table, while Haruka was absorbed in her phone.
It is a great chance to make a move.
With light, deliberate steps, Haruto got closer to Chiyo, his presence almost undetectable until he leaned in and whispered near her ear, "What are you cooking for breakfast?"
Chiyo jumped slightly, startled by the unexpected closeness. "Ah! You scared me, Haruto," she sighed, placing a hand over her chest to calm herself.
"It's the usual miso soup," she added, tucking a strand of hair behind her ear, her face tinged with a slight blush.
[You hit one of her sensitive areas.]
[Chiyo's Libido Percentage increased by 5%.]
Haruto smirked at the notification. "I see. It smells delicious." He stepped closer, taking the ladle from her hand.
"Let me help you," he offered, donning an apron and stirring the soup.
As their fingers briefly brushed, Chiyo's hand jolted slightly, an almost imperceptible reaction.
She felt a strange warmth from the brief contact. Somehow Haruto felt different today. He felt more like a 'man', a thing she craved for.
'No! Focus! Focus!' she shook her head, quickly dismissed it, focusing instead on preparing the Japanese egg roll.
She cracked the eggs and began stirring them.
"Let me heat the pan," He offered, his tone casual as he placed the pan on the stove, added oil, and turned on the heat.
"Thank you, Haruto," she said with a warm smile, genuinely touched by his unexpected helpfulness.
As their stepmother, she was used to being somewhat ignored by the siblings, so this newfound attention from Haruto made her feel a sense of acceptance and appreciation.
However, just as she was starting to enjoy his assistance, she suddenly felt a hand gripping her bottom, causing her to jolt in surprise. She turned to him, her face a mixture of shock and confusion.
"Ha—" she began, but Haruto cut her off with a low whisper, his tone laced with something she couldn't quite place.
"You know my sister and father are in the same room with us, right? What do you think would happen if they found out?"
