It was a rather normal day for Nagihiko, nothing out of the ordinary had happened at work, and as he was driving home he noticed a familiar car. The person driving it looked suspiciously much like Rima but he paid it no heed. When he got home he noticed all the lights in the house were off, which was unusual because Rima was normally home this time of the day. When he walked in and made it known he was home he got no answer. Walking into the next room he noticed a lamp that still had a light on it and went to inspect it.
Bathed in light there lay a simple white envelope with his name on it. He picked it up and looked it over. Nagi immediately recognized Rima's handwriting on the front. As he opened the letter he became more and more nervous. The house was to quiet and something was missing. He opened the letter and read it.
Half way through the letter he was sobbing. When he had finished the letter he collapsed onto the floor with tears streaming down his face. After a while he got to his feet and started inspecting the house, looking for something that Rima had forgotten, something that she left behind and would have to come back for. The only thing Nagi found was an old shirt of himself that Rima normally slept in and a stuffed toy that he won for her years ago at a festival.
That night Nagi cried himself to sleep, hugging the old shirt and the stuffed toy that Rima used to love. Wishing his chibi was there and he hadn't messed up so badly.
