125: Angry Little Sister Iroha

[When it comes to teenage girls' worries, "their own weight" is always a top concern.] 

[You used the excuse that your own computer was broken and you needed to use Iroha's computer to look up some study materials, and managed to get her permission.] 

[While she was downstairs getting water, you opened the browser history and discovered the following content.]

["How to lose weight quickly?" "Does running really make your calves bigger?" "The scientific basis for swimming to lose weight." "How long does it take for swimming to show weight loss effects?"]

[Looking at these search results, you can't help but think that the little girl who used to chase after you to play fighting games has really grown up.] 

[She used to indulge in two servings of cream cakes late at night, but now she barely eats dinner and is concerned about her figure.]

[After confirming Iroha's recent concerns, you closed the browser history and pretended to start studying the materials.] 

[Iroha returned to the room, glanced at you, and quietly lay down on the bed to read a magazine.]

[You took a surreptitious glance at her, following the line from her feet, through her calves and thighs, up to her waist which was slightly exposed due to her lifted top, and then to her delicately featured profile beneath her healthy flaxen hair.]

[From your aesthetic perspective, she is not fat at all and doesn't need to be anxious.] 

[Besides, if it were her, even if she were a bit chubby, it would be fine.] 

[She would still be cute with some extra weight. But these thoughts can only remain in your mind, as you know that expressing them would definitely invite her disdainful gaze.]

[Shortly after, you closed the computer, thanked Iroha, and returned to your room.] 

[You leaned against the head of the bed, looking at the pink alarm clock Iroha had given you last year on your desk, realizing that this might be an opportunity for you both, whose relationship has become more distant, to become close again.]

[You decided…]

[1. To show off your well-toned chest and abs in front of Iroha, enticing her to ask about your secret for maintaining your figure.]

[2. To proactively tell Iroha, "Big Brother knows a special weight loss secret."]

[3. To occasionally glance at Iroha's thighs and waist at home with deliberate attention and let out a noticeable light laugh.]

Three completely different options have appeared.

Option one is to pretend to be aloof, encouraging Iroha to start a conversation with you, thus setting up a plot development.

But will things develop so smoothly?

Considering Iroha's personality so far, he is quite skeptical about the success rate of this plan.

Option two is to directly speak as her older brother and offer to help solve her problem, regardless of how special the weight loss secret might be.

This option feels somewhat awkward. 

How would he explain discovering her desire to lose weight? Moreover, given their current relationship, it feels like even if he spoke up, he would be rejected.

Option three… somehow feels a bit petty.

But honestly, this option seems to fit the usual sibling dynamic.

Although this actions might appear a bit childish and provocative, it might catch Iroha's attention in a special way, and could potentially help rekindle your relationship from another angle, whether it's good or bad.

With his eyes gradually lighting up, Chisato felt his thoughts becoming more acute and focused.

He didn't hesitate and chose the third option.

[You chose to use a roundabout approach to provoke Iroha's dissatisfaction and create an opportunity for communication between you.]

[That afternoon, the Iroha couple attended a social event, leaving only you and Iroha at home.] 

[After washing the dishes, you went to the living room and saw Iroha in a cool home outfit, sitting on the sofa watching TV.]

[You walked over, pretending to grab a banana from the fruit bowl on the coffee table.] 

[Your gaze unintentionally met hers, and she quickly averted her eyes.]

[You, however, calmly let your gaze drift down to her waist, then slightly lowered your head to look at her thighs, which she had pressed together in discomfort.] 

[You let out an unrestrained light laugh, then deliberately pursed your lips in feigned embarrassment, turning to leave.]

[As you expected, after this series of actions, Iroha angrily called out to you.]

[The first-person perspective begins. Under this function, you can choose a certain degree of freedom in your actions…]

As his consciousness moves away from your brain, the environment's light and shadows intertwine, and his vision blurs for a moment. 

Chisato found himself in a cozy living room.

He stood in front of an armchair, facing a much shorter yet elegantly poised young girl.

"What are you suddenly laughing at, idiot!"

Iroha's displeased words came out in a soft tone.

Although she seemed to want to express anger, her naturally shorter stature made her seem lacking in confidence. 

After saying this, she somewhat regretted it and returned to sit on the sofa.

Glancing at Chisato, her nominal older brother, she nervously redirected her gaze to the TV, pulling down her top to cover some of her thigh curves with one hand and picking up the remote to turn off the TV, intending to escape back to her room.

Chisato was still surprised, clenching and unclenching his fists as he felt the new first-person perspective.

Having some degree of autonomous activity was much more pleasant than just passively experiencing things.

"Iroha, have you gained a bit of weight recently?"

Once the novelty wore off, Chisato did not forget his purpose and called out to his non-biological sister, who was about to go upstairs.

Iroha turned around, her cheeks puffing out like a hamster storing food, her hands gripping her slightly long sleeves.

"What did you say!"

"I said it looks like you've put on some weight."

Chisato walked over with the same contemptuous smile as before.

He pointed to Iroha's waist and thighs.

"Clothes that used to feel loose on you now seem a bit tight, and the shorts have become noticeably narrower."

Iroha slapped his hand away, her hands covering her chest with a look of fear as she took a step back.

"Wow—what kind of lewd brother is scrutinizing his sister like this!"

"Such an obvious thing doesn't need special attention to notice. Stop changing the topic, chubby sister."

"Go away! I'm not fat, it's just that the clothes shrank from washing!"

"And what about your face? Your cheeks are chubbier. How do you explain that?"

"Idiot… fool! Dork! Who needs to explain anything to you!"

Iroha said these words with all her might before stomping up the stairs.

"You're going to break the stairs."

"!"

Iroha stuck her head out, angrily throwing her fluffy slippers down.

Chisato easily caught them with one hand.

Iroha stormed back to her room, slamming the door loudly.
