Summer Time Machine Blues
After a series of mysterious incidents, members of the Science Fiction Club break the remote control for the air conditioner in their university club room. The following day, a time machine suddenly appears in the scorching hot room. Without a second thought, the club members travel to the previous day only to realize that if they alter the past, it is possible that the future will also change. With no practical understanding of science fiction, the Science Fiction Club members cause a troublesome time-paradox domino effect.
