This is a time-travel story caused by the use of a transformer in the women's dormitory.
No morals, no limits, relaxed writing, mainly based on real roommates.
The cause was that on a dark and windy night, five people were chatting in the dormitory, and finally decided on the roles of the five people and another sleeping roommate.
On a whim, I wrote wherever I thought to commemorate the four years we spent together.
