Hugging the World's Most Beautiful Younger Sister While Sleeping Somehow Turned Her into a Yandere - 17 - The Younger Sister’s Feelings

Runa POV

“Nii-san.”

Seeing her beloved brother sleeping while embracing her, Runa smiled gently.

Lately, she has been able to sleep while cuddling, and that brought her immense happiness.

From the first meeting, instead of strange or surprised looks, Aoi directed his kindness towards her. For Runa, who had struggled to make friends until now, it was a source of great joy. 

Though she tended to act harshly when faced with kindness, recently she has become more honest about her feelings.

She has been able to be honest in taking care of him partly because Aoi had been expressing his kindness every day without breaking, and, to be blunt, because she felt sorry about his sprain. 

Today’s bath was quite embarrassing, but in the end, I was able to wash his back.

Feeling elated after sharing the bath as siblings, Runa found herself unable to sleep even though the date has changed.

“Nnya… Runa is… beautiful again today…”

“Are you dreaming of being with me again? Your siscon tendencies have really rooted to the core.”

She lightly flicked Aoi’s cheek with the pad of her index finger. It might sound like a sarcastic remark, but she said it out of joy. Because he’s dreaming of being with her, not that girl, Minami.

She can’t erase the past where Aoi had a childhood friend like-sister, but the future is different. No matter what, she must keep Minami away from Aoi. 

It would be fine with someone else, but Minami has a history with Aoi, and he still shows a soft side to her.

If she let her guard down, Minami might take her brother away.

For Runa, that was the most important thing to avoid.

“I absolutely don’t want Nii-san to go away.”

If Aoi gets a girlfriend, they won’t be able to sleep together anymore, and he might stop being a siscon. 

It might be odd for an adolescent girl to constantly be with her big brother, even if it’s out of obligation, but for Runa, these past few days of sleeping together have been the most precious moments. 

Just the thought of not being together anymore brought tears to her eyes. 

“Nn… always… together…”

It was as if responding to her question, which made Runa’s smile become even more pronounced. 

Being together constantly made her never feel lonely, and above all, she can be with her beloved big brother, Aoi.

Whether there are romantic feelings for her brother, like in fiction, remains uncertain. However, Runa is convinced that she cannot bless Aoi having a girlfriend. She might even suggest breaking up, or if necessary, she might try to seduce him. 

If her boyfriend were to have a physical relationship with his sister, she would surely break up with him.

However, a physical relationship is the last resort. For now, she aims to stay together as much as possible and avoid making Aoi conscious of other girls.

“I will always be by Nii-san’s side. Because… I’m a brocon.”

She whispered into the sleeping Aoi’s ear, her face close to his. 

Normally, he would react to such words, but now, as expected, there was no response. Given the level of resistance he had shown earlier, if he were to react, she would doubt if he was really asleep. 

However, the lack of response was expected.

But precisely because he’s asleep, she can be honest now. When Aoi is awake, she can’t be straightforward and sometimes ends up spewing venom as usual. 

Although she wanted to be honest all the time, embarrassment prevented her from doing so.

“Let me feel Nii-san’s warmth every day.”

Without Aoi’s warmth, she feels like she might go crazy from loneliness. 

The reason she ended up taking a bath together was to take care of Aoi, who was having trouble with his sprained wrist. She thought it would be impossible to live without being together. Simultaneously, she felt as if the light had disappeared from her eyes.

Perhaps, she pondered, she might be a yandere character occasionally seen in anime. 

She understands that having affection for her brother implies something is wrong with her. Even if she’s a yandere, Runa doesn’t feel uncomfortable. 

It’s precisely because she’s a yandere that she can have affection for her brother. If she wasn’t a yandere, she might have felt grateful but wouldn’t have become a brocon.

“Thank you for remarrying, Mom.”

Because her mother remarried, she can be with Aoi, and Runa expressed gratitude to her mother, who is enjoying her trip. With that, she closed her eyelids to sleep.

Of course while hugging him.
