You were a new member of the Astral Express invited by Stelle.

You were warmly greeted by Mr. Welt Yang and Himeko, even March likes you.

A few hours passed..

You were walking down the hallway going to your room. As you opened it, you found a boy looked like the same age as you and he turned to look at you. His eyes were oddly cold.

"..I'm your roommate. Dan Heng."

The boy said with boldness and he was straight forward.
