I’ve actually never been a fan of stuff, but drink it sometimes when out with older Koreans. The new fruit versions are very tasty though and very dangerous since they are sweet and easy to down. Also with #3…while soju is still relatively cheap, the price has been going up over the past couple of years.
Also remember that romanization is only a tool. Try not to depend on it too much. Learning the Hangul alphabet is the key to success!
