the only theory i could think right now:
1) They knew they are in shit trouble atm, and Scarle is getting terminate soon
2) Right now there is #whereisScarle in twitter
3) They do not want to repeat the mistake of Selen incident, so the smart management think an alternative way to save the PR disaster
4)Tell Fulgur to use his PL accont to tweet that Scarle is okay, and also write a new hashtag #hugsforscarlento overthrow the #whereisscarle in twitter
5)After this is done, Fulgur and Aster could use this hashtag to promote the hashtag, and save the PR disaster. Since this hashtag is not artifically generated by the KuroEN management themselves, so the fans or community would not suspect anything
The KuroEn management thought this is a perfect plan, but they thought everyone is stupid, and wouldnt know the Fulgur PL acc is belong to Fulgur, and making such strange moves.
