"Would you like to join us?" Prince Elwin asked Delilah out of courtesy, and Katherine, who was about to leave for her room, paused and looked at the other two people standing beside him.

The look on Tianna's face clearly said that she wanted to spend some time with the prince, while the elder Prince didn't look like her presence would matter. 

"I need to do some assignments since I chose computer science as my elective. Please carry on," Katherine said before she turned around and left.

As soon as Katherine reached her room, she jumped on the bed.

She kept looking at the ceiling for god knows how long, thinking about how happy she was when she rode that bike before she remembered something.

"So?" 

"So?" Her system asked.

"How many points did I earn? Didn't you say I would earn brownie points if I kept advancing towards Prince Elwin?" Katherine looked at the system hopefully, who rolled its eyes at her.
