Several transliterations are possible, depending on the pronunciation you want to emphasize:
* 브라이언 (Bura-i-eon): This is a common and fairly accurate transliteration, capturing the pronunciation closely.
* 브라이언 (Bura-i-on): This is a slightly shorter version, sometimes used.
Therefore, you would write 브라이언 (Bura-i-eon or Bura-i-on) and pronounce it something like "Boo-rye-on" or "Boo-rye-un." The exact pronunciation will vary slightly depending on the speaker.
