"Gloomy Fox Outfit Set" and "Ram Horn Witch Outfit Set" disappeared from pearl shop.

I wanted to buy these two outfits for my characters. But after buying for my Maehwa character, they cease to exists. From what I knew and seen, these two outfits will be disappeared in April and June updates (Limited Edition). I want to know if they can be return so I can buy these costumes for my character. Please return these outfits, I don't know if this is a bug or you willingly deleted them. What is the problem and if willingly, are you going to return them or not? Please kindly inform me. Though I won't stop playing this game for some outfit, but if you return them, I will more than happy to buy them. And lastly, thank you very much for reading my problem.

 

Yeah it wasn't supposed to be a permanent thing.

 

Yeah bro, but in the description they said, it'll remove in April and June maintenance update. So that's why I posted this. Is there no GM who can enlighten this topic. Oh and also there are another two outfits like angel and demon queen set, those two also disappeared. Though I don't need them.
