After I Comforted My Younger Stepsister Who Had Her Boyfriend Taken From Her, She Started Becoming Obsessively Sweet - 2

Chapter 2: My Stepsister Was NTR-ed

ーーーーーーーーーーーーーーーーーーーー

This incident happened on a totally ordinary day. After returning home from school, I opened the front door only to find my little sister, Shikino, huddled on the floor with her knees pulled up. She was crying at the entrance, right in the area where we took our shoes off. There was no way I wouldn’t be surprised. I let out a small sound and flinched. In response, Shikino immediately looked up at me. 

How long had it been since we looked at each other like this? We never got in a fight or anything of that sort, but it would be an understatement to say that our relationship was good. We first started living together when I was in the fourth grade and she was in the third, but the emotional distance between us hadn’t changed since then. Whenever I tried to talk to her, my sister would quickly look away and run off somewhere. Even though we weren’t related by blood, but I wanted to become someone Shikino could depend on as her older brother. I wanted to be on friendly terms with her. But… Reality wasn’t so sweet.

Even now. I knew my concerns would only go to waste. I knew I would be playing a losing game, but I still couldn’t ignore my little sister, who was crying there with her knees hugged to her chest. Seeing the tears streaming down her face, I bent down a bit and called out to her. 

“Shikino, what’s wrong? Why are you sitting here in the entrance? Did something happen?”

“O-Onii-chan…! …”

She looked up at me, seemingly about to say something, but she quickly decided otherwise. Shikino quickly stood up and bolted down the hallway. She literally ran up the stairs and a moment later, I could hear the sound of a door slammed shut. She must have gone to her room. 

“Haah…”

I couldn’t stop myself from letting out a deep sigh. 

Why is Shikino avoiding me that much?

I never did anything wrong to her as far as I could remember. After all, I was trying to get closer to her since we were little. Nothing made any sense. Or maybe I was acting like a creep without realizing it? In that case, I had nothing but regret for my past actions, but it was too late to do anything about it. The only thing I could change was the future. 

Though my steps felt heavy, I still climbed the stairs and lightly knocked on the door with a cute plastic sign that read “Shikino.” I spoke gently, trying my best to not scare her. 

“Shikino? You don’t have to open the door, but could you please listen to me?”

….

No response. Well, that was to be expected. I already knew she wouldn’t give me any response. 

“I just want to tell you if something sad happened, I’m here to listen, okay? Mom and Dad have been really busy with work lately, so they’re going to come home late today.”

…

“Mom asked me to make dinner today, so I will make something tonight. Shikino, you like hamburg, right? I remember you really liked it when you were little.”

….

“Just wait a bit. I’ll call you when it’s ready. I’ll make hamburg for you right away.”

In the end, Shikino never gave me any response. I didn’t know what had happened, but I never saw my little sister this sad before. Unpleasant words like “bullying” and “harassment” crossed my mind. I wanted to believe that someone as popular as Shikino wouldn’t have to deal with that, but I couldn’t say that for sure without any definite proof. Albeit still feeling anxious, I descended to the first floor and started making hamburgers just as I had promised.

That night, Shikino didn’t come out of her room even after Dad and Mom got home. She stayed holed up in her room. However, it seemed she still ate the hamburg I made for her since the food I had left in front of her door was empty. It looked like she still had an appetite, so she didn’t cry because she was feeling sick. However, this made me even worried about what had happened. 

Shikino still refused to come out of her room the next morning. It seemed she was going to skip school today. Dad and Mom were worried about Shikino too.

Just what happened to my little sister? While bearing the worries on my back, I reluctantly headed to school. Still feeling down, I entered my classroom in a daze and took my seat. But then, while I was staring blankly into space…

“Yo! Besties! What’s up? You look like a dead fish, staring off into space first thing in the morning!”

A guy cheerfully slapped me on the back. It was my best friend from middle school, Takumu Marukawa. He was full of energy, just like usual. I let out a tired sigh and gave him a nonchalant response. 

“My eyes are always dead, so just leave me alone. I’m thinking about something.”

“Thinking??? You, Mamori????”

“What do you mean by that?? Just so you know, I have a lot on my plate, okay??”

“As if! Your head is probably filled with thoughts of that super cute little sister of yours.”

“I-It’s not full of her! Stop with that misunderstanding!”

Good grief. What is he talking about? My head is not full of Shikino…. I think. I mean, yeah. No, really. I mean, I do think about what I should do to get liked by her, but that’s not the only thing I’m focused on. 

“Ah, by the way. Do you know? About your little sister?”

“Huh? What? Did something happen to Shikino?”

“What, you seriously don’t know? Well, you two don’t get along well after all. Ah, I see. That’s why you’re so gloomy.”

“Shut up. So what happened? What happened to Shikino?”

I asked and Takumu looked around cautiously before he leaned down and covered his mouth with his hand as he whispered to me. 

“I heard Shikino-chan’s boyfriend was taken by another girl.”

“…Huh?”

“I just heard about it through the grapevine. Like how Shikino-chan is too clingy or something and to make it worse, Shikino-chan got NTR-ed, just like my big sister.”

“…Huh…”

“Even though she’s so beautiful and cute.. The girl that snatched her boyfriend is one thing, but the boyfriend himself, man! He’s a fool! Shikino-chan is super beautiful! Getting tied down by someone as beautiful as Shikino-chan is a blessing!”

My best friend explained while moving his body exaggeratedly. However, I was so shocked by the fact that I couldn’t care less about his antics.

Shikino’s boyfriend was taken from her. It sounded like a lie. Shikino never dated anyone, so it was really hard to believe her first boyfriend would actually cheat on her. 

“…I see… So that’s why Shikino…”

“Huh? Did you say something?”

“…No, it’s nothing.”

I couldn’t focus on my class for that entire day. I kept thinking about Shikino. I knew I had to comfort her as soon as possible since she must be feeling so down. My mind was filled with the thoughts of comforting Shikino.
