There are so many days for couples 😘 and singles 😉
한국에는 커플과

싱글들을 위한 날들이 참 많아요.

Ah ! I didn't know the difference of swapping couple rings between Korea and Western countries :
"Couples celebrate their first 100 days by exchanging gifts, often the male expected to spend exorbitantly, and couple rings may be swapped. While in the west couples don’t often have rings until they are engaged or married, in Korea, couples often have rings when they’re dating. To go all out, some couples even make their own special rings. "
