Jewelry, Roses and Chocolates. Valentine's Day (technically Saint Valentine's Day) is a big deal, and boy do writers know it! The holiday on February 14 has been used a million times in all sorts of media to bring up love and romance. White Day is a similar holiday observed in Japan and South Korea on March 14. In some countries, it's normal to give Valentine's Day cards or gifts to friends, whereas in other countries you'd only give a Valentine's Day present to someone you are romantically interested in, leading to a bit of Values Dissonance for certain audiences.
