AFTER walking out of the mall, the twins didn't dally any longer and went straight to the building where the apartment Astrid rented was. They were afraid that if they went to another place, they would encounter something they didn't want to encounter again. It's better to be safe than sorry.
They just finished talking to the landlord of the apartment complex. Astrid signed a one-year contract for the apartment and paid for it. He had enough star coins in his savings account to pay for a whole year of rent. After all, their parents weren't exactly cheapskates when giving their children money.
The twins went up to the 20th floor where Astrid's apartment was. There were 10 apartments in each floor. Since his apartment number was 2010, one could easily presume that it was the apartment at the very end of the corridor after getting off the elevator.
