Larven is a young man from America who has dreamed of exploring the universe since he was a child. His father, an amateur astronomer, often took him stargazing with a small telescope. This interest grew into an obsession, and Larven was determined to be part of space exploration.

To make his dream come true, Larven successfully joined ENCEI (Exploration and Navigation of Cosmic Engineering Institute), an international organization that serves as a hub for space research and exploration. ENCEI is where experts from various countries gather to study the cosmos, space technology, and advanced navigation systems not taught at regular universities.

There, Larven met a quiet girl from Indonesia who is known as an outstanding student, an expert in navigation systems and medicine, with deep knowledge of extraterrestrial ecosystems. Though Larven initially thought she was difficult to approach, he became curious about her mysterious side. He often saw her sitting alone in the library, engrossed in reading journals about survival on foreign planets or writing complex notes about interplanetary gravity theories.

"Why is she always alone?" Larven thought one day, as he saw her working alone in the gravity simulation laboratory.
