### Summary
Still reeling from past failures and the knowledge that the asteroid "Rama" is an alien weapon, Cheolsu and his team are engaged in a 20-year plan to develop a warp engine. Their progress has been critically stalled by their inability to decipher the weapon's alien language, forcing a stressed Cheolsu to personally study complex scientific principles. In a pivotal breakthrough, Yumi, whose non-scientific role as a "money maker" had been questioned, proves her essential value by apparently solving the linguistic puzzle. This solution reveals new, perplexing information about the weapon's fundamental nature, leading to speculation that its motive might be a simple, almost biological need, metaphorically described as being "thirsty." As the team moves forward with this new understanding, an astronaut on the team is noted for a quirky personality, while Cheolsu continues to avoid a figure named Charlotte and the group awaits the return of Dr. Odelie.
