At a very nice and prestigous school in Korea there were two students who fell in love, but will that love last?p

As Jimin had to go to a different training center, his crush and really close friend Yoongi feels that one week feels like one year while her roommate/friend, Taehyung enjoy the rest of the week.

After the end, only some people survived. They were brought into a different world, a different dimension.
