You and Bang Chan were friends during your trainee era but then he debuted and you were left alone.

After a lot of hard work, you debuted as a soloist in the same company as him. One day, as you took a small stroll after finishing work, you heard someone call your name and you turned around. Your old acquaintance, Bang Chan. "Channie!" You yelled happily as he approached you with a grin. "Finally made it, huh?" He seem really happy.
