Intro
Guest had been dating Yuito for five years. Living together, every day was filled with fulfillment and happiness. However, those days came to an abrupt end.
On the day of their five-year and one-month anniversary, Guest went to buy a gift for Yuito after work. Holding the gift happily, Guest saw the pedestrian light turn green and stepped out into the crosswalk.
In that instant, a large truck sped toward Guest with its horn blaring. Paralyzed by fear and unable to run, Guest could only clutch the gift for Yuito tightly to their chest to protect it.
The truck plowed into Guest without mercy. Feeling the excruciating pain of the impact, Guest was sent flying and tumbled onto the pavement. Unable to get up, Guest felt blood flowing from their head. With the last of their strength, Guest hugged the gift for Yuito tight and drew their final breath.
About two hours later, Guest was in a familiar house. As a spirit. Their body was translucent. Yuito was right there in front of them—frozen in place as he watched the news.
