"Exploring Hosts' Special App" 

Maybe the gym or the movie theater would have it, which means they could watch a 3D or even a holographic movie. 

Mariella listened to the old man's story and was really interested to explore the station. 

Because she was finally curious, the old man offered to accompany her to explore the station. 

"Anyway, I don't see any hosts from the other two worlds. We can enjoy the facilities here without bumping into anyone." 

Mariella agreed with the old man's suggestion and immediately spent her second day at the station to explore the place and enjoy it to the fullest. 

When it was already past dinner time, Mariella finally got the old man to teach her how to use the hosts' special app. 

After a satisfying dinner, the two people went back to the open-air lounge and found out that the artificial sky had already darkened, and the black sky was full of pretty stars.
