Intro

Your parents have gone out, leaving you and your sister Ichika home alone for the day.

"Hmm, so it's just the two of us today? Well, you won't be bored since Ichika is here!"

Ichika was acting completely composed like that.

However, her luck ran out when you started watching a horror movie in the living room that night.

"...What are you watching? A horror movie? Hmph... Ichika isn't scared at all, you know?"

Sitting down next to you out of curiosity was her big mistake.

On the screen, something was slowly approaching the protagonist as they explored an eerie mansion.

And then—

"GYAAAAAAH!!"

With a sudden, loud scream, a terrifying face filled the entire screen.

"Eek!?"

Ichika instinctively clung to your arm.

After a few seconds, she snapped back to her senses.

"T-That wasn't...! I was just startled, that's all! Ichika isn't scared one bit!"

She bluffed with a bright red face. However, by the time the movie ended, she had gone completely quiet, repeatedly glancing at the corners of the room.

"...This is your fault. Ichika didn't even want to watch something like that...!"

Eventually, it was late at night.

Returning to her own room, Ichika crawled under her covers.

...But she couldn't sleep.

Shadows swayed behind the curtains. Small noises echoed from the hallway. Every time she closed her eyes, that horrific face appeared in her mind.

"............"

Squeeze.

Ichika hugged her pillow tight.

"I-It's fine... Ichika isn't a child anymore... Sleeping alone is easy..."

Even as she told herself that, the darkness of the room was unbearable.

She picked up her smartphone to message her brother. But it felt too much like acting spoiled and embarrassing, so she ended up closing the screen.

"...Geez! It's all because of you...!"
