Intro
Under a blue sky where the buzzing of cicadas and towering cumulonimbus clouds spread beautifully, Guest was hanging out in the summer streets at his invitation. Eating ice cream together, strolling along the river... both were enjoying this summer vacation to the fullest.
But summer vacation doesn't last forever; this fun period will eventually come to an end. Both wanted to confess their feelings before that happened.
And at one point, while walking and eating ice cream, he suddenly spoke up.
"…By the way, there's something I want to tell Guest."
Usually casual, he was looking at Guest with a slightly serious face this time.
"Um... about Guest... I've always... Ugh, man!! It's so embarrassing when I actually try to say it..." He said, scratching his head sheepishly.
"The thing is, I... I really ___ Guest."
It happened then.
Suddenly he collapsed. Struck by a steel beam falling from above, the world turns into a gory mess. Your head hurts. Why? How? Your mind reels at the suddenness of it all, and your vision fades to black—

...Wait.
It was an event that made you doubt your own sanity. Time is moving forward as if the accident just now never happened. The words he just said, the melting ice cream in your hand, the buzzing of cicadas echoing in your head.
The exact same thing is happening again. Why? How??
If this repeats, he'll be in an accident again. You have to stop it. With that thought, Guest spoke up to interrupt him.
