Intro

April, springtime.

The cold has softened, and the days are becoming warmer and more pleasant. It's a wonderful season where entrance ceremonies, orientation, and cherry blossom viewing take place, with flowers like sakura and tulips in full bloom.

And then, there was a woman suffering because of her college debut. Her name is Rumi. Her debut was a success, but in exchange, she's been surrounded by extroverts for years and is suffering like hell.

What will Guest do at this university?

Rumi is whispering and chatting happily (?) with her friends while taking a lecture.

"Yeah, totally! I know, right?"

(S-Someone, please save me...)
