Korean girls, sorry, I don't know, haven't experienced before. Japanese girls, yes, Valentine also they buy gifts, Birthday also they buy gifts, Christmas also they buy gifts, nothing else to do after just a good romantic night, the morning after they also go and buy gifts. For them, it's not as simple as gifts, the meaning is memento, something to remember a day they consider memorable, something from the heart, doesn't matter how much comes from the purse.
