If you are still single or became single when the clock ticked to April 14th, then maybe you might as well consider celebrating Black Day with your firends who are also singles.
Korea celebrates Black Day every April 14th as an answer to Valentines Day (Feb 14th) and White Day (Mar 14th). This is a Korean informal tradition for single people to get together and eat jajangmyeon (noodles with black bean sauce) and sometimes a white sauce is mixed for those who did not celebrate White Day.
The idea is that those who did not give or receive gifts on Valentine's Day (February 14) or White Day (March 14) can get together and eat jajangmyeon (자장면), white Korean noodles with black bean sauce (hence the name), to celebrate their singledom
Of course this is also known as "Singles Awareness (or Appreciation) Day" (SAD) in other countries, only that SAD is usually celebrated on February 14, others may prefer 13th or 15th, against the celebration of Valentines Day for couples.
