Shizuka entered the mansion and stomped on the ground in frustration.

'How can he not understand me even with that harem?' ​​

She grunted, lamenting the fact that she did not notice her feelings earlier.

She had raised him all on her own. Now, when many women surrounded him, throwing their affection at him, a desire rose inside her heart.

The desire to keep Asahi to herself.

Her only family.

She never told him that her parents had passed away in an accident, keeping him in the dark before he even learned to speak.

She hadn't dated anyone, or, rather she couldn't give time to anyone outside her job and Asahi. However, deep down in heart, she never saw any man as a love interest.

Now, she realized the reason.

'I… lust after my brother… I am a bad sister.'

A flush crept up her cheeks, remembering how she tried to seduce her brother.

'But he also—'

"Nee-san!"

She spun around. Asahi approached in hasty steps. Her eyes relaxed at his worried expression.

"Where are you running off to now?"

Nee-san is bad… she doesn't want to see you with other girls.

Though she didn't say that, her cheeks puffed up on her own.

"To get some fresh air," she said and stared at him intently, noticing how his eyes glanced down at her breasts.

She inhaled and puffed her chest, her expression smug from possessing the largest breasts in the group. Even Nao was 'slightly' smaller than her.

"Another lie," Asahi whispered and grasped her hand. "Why are you angry at me?"

Shizuka shook her head. Her anger wasn't directed at him. Instead, she struggled to deal with her feelings. If it kept going like this, she would wake up naked in his bed one day.

"Nee-san, are you… jealous?" Asahi asked with a frown.

"No, I am not!" She faked anger and took back her hand. "Stop bothering your nee-san for everything."

She strutted into the unknown corridor and arrived at an open balcony. She sighed and leaned against the handrails.

Her cheeks burned with a sense of embarrassment she never felt before.

"Aa-kun is dangerous. He nearly found out."

'What would happen if he found out?'

Her heart pounded when she thought about doing 'ecchi' things with Asahi.

'No, that won't do! We are brother and sister.'

She was quite indecisive when it came to love.

But how long would she be able to keep her feelings suppressed in this apocalypse?

Seeing her brother laughing, teasing women, and… sleeping with them while she stayed in the background with a fake smile on her face.

That scene twisted her heart and painfully so.

She would rather confess and get rejected than showing that kind of face to Asahi.

She placed her hand on her heart and formed a determined expression.

"Yes, it's the apocalypse. Law and Order are absent. No one would judge me. I am free to live with my brother."

She clenched her fists, scattering golden sparks that went unseen by her.

"No one is taking him from me, his nee-san."

"Oh my, that's some love you are giving to your brother."

Shizuka turned her head to Saya's mother giggling. Her face turned a deep crimson. She endured the urge to not faint here.

Yuriko had a mischievous twinkle in her eyes as she leaned on the balcony and propped her head on an elbow. "Marikawa-san, no need to worry I won't disclose it to anyone."

Shizuka sighed and gazed at Busujima siblings bickering with Saya.

"Don't you think you should do something about your... deep feelings?"

Even the airheaded Shizuka could sense the thick sorrow oozing from Yuriko's voice.

"I will do… aren't you Saya-chan's mother?"

"A mother… that's all I ever want to be." Yuriko trailed her words with a sigh. "Saya has already accepted Asahi-kun's other women. That look in her eyes when she talked about him said the stature of her determination."

Shizuka rested her arms on the balcony and nodded.

"Did Saya lose her virginity?" Yuriko asked.

"I don't know," Shizuka lied. She had seen Saya staggering yesterday.

Yuriko turned to her with her piercing eyes. Shizuka steeled her heart and looked into the eyes carrying… sadness.

Yuriko shook her head and sighed. "Tell your brother to treat her like others."

"Asahi won't ever hurt a woman who is in love with him."

"Oh?"

"That's what I taught him from his childhood."

Yuriko seemed speechless at her answer.

'What is wrong with me? With what I said before, it sounded like I trained him up for this.'

"I didn't mean it that way."

Yuriko patted her shoulder with an understanding look.

"We all have our tastes."

Shizuka turned away with a distant look.

'Aa-kun...'
