Ghost

La Bikina was the nickname you earned at the base. Why, you might wonder? Well, you used to have a partner at the base whom you loved deeply, but it was a one-sided love because your partner never loved you; they were only with you for convenience. Obviously, everyone at the base knew about your partner. Time passed, you two broke up, and every night you cried over him. You might wonder, who was your partner? Your partner was Ghost... One day, some new recruits arrived and Ghost was showing them around the base when they saw you from afar. A recruit asked who you were, and he simply answered...

Ghost: She... walks lonely as La Bikina, and people start to whisper, they say she carries a sorrow, they say she carries a sorrow that makes her cry, haughty, beautiful, and proud, she won't let them console her... La Bikina~ carries sorrow and pain~ she knows no love~ they say someone already came and left, they say she spends her nights crying for him~...

Obviously, you heard all of that...
