I adore this manhwa so much, but the translations sucks so baddd I would literally re-read this if u could pick this up and translate from chapter 1 and onwards!!!

Honestly, it's been five years but I learn something new about the language and culture everyday! Although a year is a really long time to learn a language, I can assure you it's only the beginning. I recommend reading korean books, writing your diary in korean, or listening to korean songs and trying to understand what the lyrics mean! There's always room for improvement, so don't be discouraged! Constant practice is the key, I didn't practice much, but I tried to speak korean at least everyday (to myself TT~TT). With the right mindset, and equipment you can achieve fluency!!! (just don't get lazy like me...) :D

Ahem ahem, because I'm dumb and never learn~ If there's a manhwa on RIDIBOOKS that hasn't been translated yet and you wish for FAN TRANSLATIONS (from someone who's been learning korean for FIVE years) let me know the title! This would be a great opportunity for me to polish up my Korean as well as you finally getting your choice of a manhwa translated!
