Haein took to LABOUM's official Twitter to post photos of her and Lovelyz's Kei, who evidently remembered Haein's birthday and brought her a mini cake backstage at 'M! Countdown'! Haein thanked Kei, writing, "Kei who bought me a cake for my birthday... You could've just let it pass by but you took care of me by remembering it, and I'm totally touched. T.T Thank you so much."
Happy Birthday Haein!
