I'm not familiar, [ which is true. tseng became familiar with valentine's day during the month of his arrival, but he never did get introduced to white day as a concept. ] Eiden must have an impressive influence on your world, to create a new holiday that way.

[ why people would need a holiday specifically for gifting chocolate is somewhat beyond tseng, of course... but far be it from him to denigrate another world's holidays! ]

What happens during Idol Fest?
