There are many things in this world that science cannot explain. That's why people have forgotten them and call them strange tales and oddities.
After an accident, I was reborn in a parallel world.
On my very first day after reincarnating, I became someone else's girlfriend.
And the System is with her, too. How am I supposed to escape her clutches? But what I didn't expect was that, most importantly, she wants to turn me into a submissive bottom.
How am I supposed to survive this?
Even more unexpectedly, my best friend transmigrated here with me and became the bratty little girl he loves most!!!
System, female characters, pure love or gender-bending Yuri? School setting, sweet story, probably no angst.
