In fact, she never thought that she would travel through time. Of course, she never thought that she would be in the world of the Net King before meeting Tezuka.
The heroine knew about Net King but didn't finish watching it. The story took place when Tezuka went to Germany to recover from his injuries.
The heroine is not omnipotent, and she is a 2.5-Dimensional person who likes ACG = =
ps: Actually, I don't know how Tezuka fell in love with that bastard, but since they did, they fell in love with him!
Ps of ps: Most of the stories in Europe are the author's own experiences. Don't slap me if you know the truth. I just want to YY Tezuka in Germany>_
