About [My] <em>my</em> Nickname

Hi! I'm back after a long time away.
Today, I want to talk about my nickname.
I have a nickname<em>,</em> "kaka". People [maybe] think that <em>maybe</em> I am a fan of <em>the</em> football player, who is also called "kaka"
In fact, I didn't <em>even</em> know [him] <em>who he was</em> when I [have] <em>chose/got</em> my nick name.
I'm an ethnic Korean <em>living</em> in China, and the last word of my name in korean [pronouncate] <em>is pronouced</em> [as] "ka".
[So] <em>For this reason</em> my friends always called me "kaka" , that's [the reason how i have] <em>how I got</em> my nickname.
[Even] <em>I know</em>, it sounds like <em>a</em> boy's name, <em>but</em> I still like <em>to</em> use it[. Because] <em>because</em> it's easy to remember.
