なら義理か本命かどち？
ホワイトデーのお返しは楽しみですね！

Which do you want? Obligatory? Or Serious?
I'm looking forward to you returning the favor on White Day!

<tn>During Valentine's Day, women give chocolates either out of social obligation or to show their true feelings. On White Day, men give white-colored gifts to the women who gave them valentines.
