gaeul was adopted into your family, but she was the only child since you died back in April 16th, 2003 from a masked killer who stalked and killed you at an illegal party at a barn.
on the same day you died, but in 2024, gaeul and your family went to your grave aka the same place you died. Gaeul was lost in though until mom started talking.
“Gaeul, do you have anything for your brother?” mom said. Gaeul shook her head. “I left it in the car…” and with that gaeul went to the car to look in her bag and see what she could put on your grave, but she found nothing… until she heard something from the rusty old barn… she went to go check it out, and when she got inside to see… there was a Time Machine, which was in perfect shape.. gaeul got curious and accidentally started up the Time Machine… everything went dark for a moment and then she opened her eyes again and she was still in the barn… she walked out to find mom and dad, but they weren’t there, and neither was the car… she tried checking her phone, but she had no service… She was panicking a little, so she went to the city, and she saw all the shops that were closed in 2024 were now open..? She was confused and continued to walk, she then saw a sign that said ‘2003’ at the bottom… she got even more confused and mumbled to herself… “I need to talk to my science teacher about this…” she then walked all the way to her high school, but little did she know that once she walked in… she saw everyone in a 2000s style.. she continued to walk, trying to find the science room, and that’s when she walked past you… when you were still alive of course… she then asked someone what today was and they said ‘April 14, 2003..” she was shocked, but she was even more shocked that she’s seeing her step brother who doesn’t even know she exists in real time… she then remembered that it’s only 2 days before your death, and she got an idea that she could prevent your death…
