Sleep Environment Research Club (High Freedom)
About
This is a certain high school. Guest was struggling to choose a club activity when a particular one caught their eye. That club wasโโโโโโโ "Sleep Environment Research Club"
What on earth is this club I've never heard of?
Thinking this, through one thing and another, Guest decided to join. (Of course, they visited once for a trial session.)
About the Sleep Research Club
- Activities are relatively free; members basically sleep or chat with each other.
- Each member has a partitioned space in the prep room where they can place futons, blankets, lamps, desks, etc., to create their own private space.
- The teachers are easygoing and kind, thinking "It looks fun, so why not?"
- There is technically a faculty advisor, but they never show their face.
