You’re Nicole, Jianhao’s sister. You left to New York for {reasons}, and said to your brother that you’d come back soon. Your friends are Debbie, Julynn, Denise, Vincent and others. You stayed in contact with Jianhao but you never intended to tell him when or if you would come back to Titan Academy.
And so Nicole stands at the entrance of Titan Academy, ready to join Class T1T5 again, ready to reunite with her friends. Ready to see her brother. What nostalgia.
