This Is How South Korean Couples Do PDA
Public displays of affection for couples are usually things like holding hands, kissing, hugging, or other appropriate forms of loving touch. Couples in South Korea show that they love each other by doing something different-matching their outfits. By wearing clothing that matches the clothes of his significant other, one man said it showed that they were on the same team in a similar way to sports players wearing the same jersey. This trend is called Keo-Peul-Look (커플룩), which means "couples look."
