I think everything started from watching Digimon, Neon Genesis Evangelion and Sailor Moon in preschool. When I knew how to read my older brother gave me the first volume of Dragon Ball because he didn't like ''Japanese shit'' (my dads friend gave it to him) I fell in love with it so I started to search for all the other volumes in stores nearby but instead of Dragon Ball I found Tokyo Mew Mew. I found out that there was a anime of it and started watching it and when I was done with TMM I found Sugar Sugar Rune, Shugo Chara! and started to listen to An café, Miyavi and Minimoni.
Then in 4th grade I got friends with similar interests online and it was my little secret pleasure until 5th grade when my IRL friends got to know they forced me to stop liking ''embarrassing stuff'' and be normal. In 7th grade I started to watch anime again, read some BL manga,vnowadays I like yuri more than yaoi though. I also found Perfume, Mucc, 12012 and other Japanese bands I started listening to.
And that's pretty much it.
