Hangul
Blocks, not beads
English strings letters left to right. Korean builds a square.
A Korean syllable is a tile: a starter consonant, a vowel, and sometimes a closer (받침). 한 is ㅎ + ㅏ + ㄴ sitting in one square, not three Latin letters in a row.
That is why 서울 looks short and sounds like two beats: 서 / 울. Train your eye to find the squares first, then sound them.
You do not need every letter today. You need to stop treating Hangul like a decoration on a K-pop thumbnail.
