Summary

The girl, born into a wealthy family, seemingly has everything but is constantly surrounded by an overwhelming sense of boredom, prompting her to chase after excitement incessantly. Upon receiving an invitation from a mysterious man, she gambles everything in a billiards match, only to discover beneath the bandages wrapped around the man's wounds a sorrow she had never imagined. The gentle oxygen of her comfort zone feels suffocating, and perhaps only by journeying together can one catch a glimpse of the dazzling deep space beyond the atmosphere.
