February is here, and love is in the air. For many, Valentine’s Day on February 14 is a special time to celebrate love, friendship, and the beauty of human relationships. Red hearts, teddies, chocolates, and roses are everywhere—both in the real and virtual worlds. Named after the Roman Christian martyr Saint Valentine, Valentine’s Day is celebrated differently across cultures. In Europe, couples celebrate their relationships, while in Japan, women give chocolates to men—whether a special someone, a male friend, a colleague, or even their boss.
