Can you guys read Hangeul?

I can read it.

But I think I read it kinda slowly.

For hiragana/katakana, I can only read a few letters. (e.g. の)

Yes but I have no clue what it says

In 2017 I wanted to self study Korean and bought a book and followed several YT accounts who teach but after 1 month I had enough and stoped

BTW I might know like only 30 or less Korean words trought what I learned back then and I'm still laughing from time to time at the word kot

kot -> fast prounciation = flower, but based on context it can also mean face

kot -> long pronounced o = One of many words to say "poop" in German

Yes, I studied Korean for a while (5-6 yrs)

I can't read katakana though
