What a Sacred Day

Japanese people have an odd custom to give chocolate to a boy from a girl on St. Valentine's Day. I don't know exactly when this custom began. As far as I know this custom has already been spread when I was a primary schoolchild.
St. Valentine's Day gift is basically oneway in Japan. A girl gives chocolate to a boy although there are many cases in which a girl gives it to a girl as a seasonal gift mainly at girl's school.
Unfair?
Don't worry, girls. Instead, "White Day" comes just a month later. Then a boy who was given chocolate has to give something back to the girl who gave him a gift. Originally "White Day" is derived from the color of marshmallow, which used to be a typical gift which a boy gives back to a girl. However recently a boy must give back to a girl something three times of the gift he was given. Nothing is more effective than this investment for Japanese girls.
Most of chocolate gifts delivered by Japanese girls on February 14th are called "Giri Choco", which are given to boys to express friendship although St. Valentine's Day gift seems to be given only to a lover in Western world. The gift given to her steady boy or her favorite boy, which is called "Honmei Choco", is distinguished authoritatively from "Giri Choco". Nevertheless the return to a girl must be three times what she gave to him no matter which her gift was Giri or Honmei.
It might be unfair in another sense.
