As for me, My native tongue is Filipino, my second language is English. During my crazy KPOP days, I studied both Korean and Japanese. That was around 2009. Self studied Korean and studied Japanese formally (in a school somewhere out there) and I eventually reached level 2. But a year and a half after, right before I reach level 3, I have to quit formal nihongo lessons so in the end I was left to self study both language. But I focused more on hangul (because of KPOP) so I can pretty much read and write hangul with ease. As for nihongo, I pretty much suck at writing kanji. But I can read a little bit of it. Not all of course. After all, I quit formal lessons, right? So yeah.... (sorry for the very detailed explanation)
