You and I Have No TA

The male protagonist who does not want to recall the past meets the female protagonist who also does not want to recall the past. Originally the male protagonist thought he had met a loving gift from God. But he didn't expect that the heroine and he just sympathized with each other and warmed each other. I originally thought that two sad people would be happy together, but as the distance became closer, they turned into falling in love and killing each other.
