Maid Genderless

Dear Zelo

Zelo sighs opening the letter;    

Dear Junhonggie~  
I have to tell you I've been lying to you. I'm not the cool hyung you kept telling me I was. I'm your noona. That's right I'm a girl. I didn't correct you guys and I'm sorry to have lied to you.
I only went with what you guys said because I don't like talking. Too many people focus on making their words sound pretty forgetting that their actions have more of an impact. Remember this, Zelo. If you really want to be cool like me which I don't recommend, then do whatever makes you happy. The opinions of others don't matter because if you focus too much on pleasing others you lose yourself. We can't lose you Zelo.
I hope you don't hate me for hiding my true gender from you. I was just trying to help out I never pictured that we would actually become like brother and sister or I guess in this situation it's sworn brothers. Whatever our relationship is, know that wherever I am from now that I'm watching you on the television or my computer screen. I'll do my best to become the noona that you look up to as well. I know the others will lie but only you and Jong Up didn't know about my real gender. I have no idea why they kept it from you. I just know that you'll be my favorite dongsaeng.
No one else is like you and keep it that way. I wish I had something more to tell you but I don't know what else to say. You have my phone number so you can call me. I'll be in Japan after tuesday for a month. I'll answer if I see your name appear on the screen for sure though.
Junhonggie, Jin Noona is on your side~  

Zelo Fighting!

Zelo tries not to cry pulling out his phone. He had to talk to her. The gender didn't matter. He needed to hear her talk to him. She answered on the first ring.  
"N-noona?"  
"Zelo"  
"You're a girl?"  
"Yeah"  
"Then th-that time with Secret Sunbaenim..."  
"I went because you set it up. We couldn't make your sunbae mad by canceling"  
Zelo manages a laugh.  
"Can you let me become the Noona you admire?"  
"You are"  
Slight laughter and crying from the other end.  
"N-noona?"  
"Thank you"
