In The Flower, a question was left deliberately unanswered:
Who is the Mysterious Teacher?
The Rainbow begins where that uncertainty ends.
As fragments of the past resurface, the origins of the Mysterious Teacher are revealed—how he came to exist beyond ordinary time, how he learned to move through it, and what first pulled him out of the human world. What once appeared as coincidence begins to take shape as design.
But revelation brings danger.
A new figure emerges—brilliant, methodical, and deeply unsettling. Armed with a precise understanding of physics and light, he begins abducting young women, using them as part of a series of experiments that push the boundaries of space, perception, and morality. His actions are calculated, his purpose hidden, and his success frighteningly close.
As science and music collide, colours fracture, time bends, and reality itself becomes unstable. And beneath the visible conflict lies the faint presence of something far older—an unseen force watching, waiting, and quietly influencing events from the shadows.
The Rainbow expands the world of The Mysterious Teacher into darker territory—where answers come at a cost, and every revelation opens the door to something far more dangerous than ignorance.

Sukeerthi Teja Rallapalli
Sukeerthi Teja Rallapalli is a musician, educator, and music neuroscientist whose work examines the relationship between Grand Staff notation, the human central nervous system, and the piano. He is the founder of Besser Academy, where he has developed an original approach to music education by mapping music reading and sight-reading directly to human neural and
cognitive processes.
His work spans music education, neuroscience, and mental health, and includes collaborations with international academics and researchers. Through this interdisciplinary lens, Teja challenges conventional boundaries between music reading, cognition, and human perception.
The Mysterious Teacher series marks his entry into longform storytelling, where he uses narrative as a medium to
communicate and explore the discoveries and questions that have emerged from his work—allowing ideas to be
experienced rather than explained.
