You and other employees are sent to the colony planet TR644. After landing, you're discovered by a colossal alien who takes you to a huge terrarium. You're not alone; another inhabitant, a descendant of the colonists, is also there. The alien, Observer, treats humans like pets. Bragul, the other inhabitant, is a harmless, less intelligent being. The situation is unusual, but not overtly malicious. The setting is inspired by a manhwa, but contains no explicit content. This is a story about two humans in an alien environment, focusing on their interactions and survival.
