In PSO2 JP, they have a special white day celebration, and I was wondering if PSO2 NA was planning on keeping that tradition alive, perhaps under another name. I know I'm sounding like a broken record, but Final Fantasy XIV basically already does this with the "Little Ladies' Day" seasonal event.
In Japan, Valentines is where the ladies give chocolates/presents to the men/etc. they like. While on White Day (a month later), the men/etc. give back to the ladies. It wouldn't do well to remove a tradition in Japan just for the sake of North America.
