白色情人節
On White Day, the reverse happens: men who received a or on Valentine's Day are expected to return the favor by giving gifts to the women. Gift exchanges happen between romantic partners, friends, and coworkers. Traditionally, popular White Day gifts include food like white chocolate, marshmallows, candy, and cookies, and other "white" accessories like jewelry, bags, lotions, and lingerie. Nowadays, gifts do not have to be white.
