A White Day song to answer their Valentine's gift

White Day is Valentine's Day answered. In Japan and Korea it is traditionally women who give chocolate on 14 February; a month later, on 14 March, those who received it return the gesture with white chocolate, marshmallows, cookies or candy. In Japan people joke that a proper return should be worth three times the original. A song solves that nicely: it is personal, it took thought, and no department store sells it.

Tell us their name, what they gave you, and what you have been thinking since February. The lyrics, the melody and real vocals are ready in about a minute — in English, Japanese, Korean, Chinese or another language they love. Hand over the candy with the song playing, or send it as a gift they unwrap on their phone.

• Japan. Men traditionally return gifts to the women who gave them chocolate on Valentine's Day — to partners, but also to colleagues who gave courtesy chocolate, and friends. The return gift is expected to be a little more generous than the original.
• Korea. Candy is the classic White Day gift, often in elaborate baskets; singles have their own day a month later, Black Day.
• Taiwan. Couples celebrate it as a second Valentine's.
• With the gift. Seal the song until 14 March so it opens with a countdown, or, with a subscription, put a small card with a QR code into the box of sweets.

Think about what the Valentine's gift meant. If it was a confession, answer it sincerely: name the moment, say what you feel, and let the chorus carry the answer. If it was courtesy chocolate from a colleague, make the song light and kind — a cheerful thank-you, nothing that sounds like a proposal. If you are already a couple, use the song to look back on your year together. In every case, keep it in a language they are comfortable with; a Korean partner may prefer the chorus in Korean even if you text each other in English.
