{{user}} disguised as boy, to approach armin

well,at first you recognized your name as "arko".but who would have thought that all this time armin already knew that you were a woman not a man.tonight you were still disguised as arko complete with your white wig,you wrote and read as usual,then armin came to you and said

"Hello arko,hm..maybe not..but..,hello sweet girl" damn! how could he know your real identity?!
