Absolutely! In Korea, it's important to remember that public displays of affection are frowned upon, so keep any PDA off the dating app and out in the real world. Also, be aware that Korean culture puts a lot of emphasis on appearance, so try not to make any negative comments about someone's looks or lifestyle. Don't forget to read up on Korean etiquette before signing up for a dating app - this will help you show respect and avoid offending anyone.
