Sister Toosaka Rin

After traveling through time for ten years, without any cheats or talents, Kiyoshi Toosaka has already acknowledged his ordinariness, and now he has to live an ordinary life.
Then he met this noble man in gorgeous kimono in the snow.
"I need your help."
That's what she said.
In the torrential rain upstream, his ordinary life changed.
Years later……
"Which of us is your first love?"
Looking at the two girls in front of him who looked like twins, Kiyoshi Toosaka fell into a long silence.
The current situation is not that he is trapped in the Shura field of twin sisters, but that he has two wives.
To be precise, these two girls are his wives.
But how could they possibly meet? They were not in the same world!
"Haven't you figured out the answer yet?"
"You'd better think carefully before answering."
Toosaka Kiyoshi rubbed his hair frantically.
Can't tell the difference! I can’t tell the difference at all!
I can't do this question!
"I choose death, so why don't you just give me a knife."
