     'Happy Birthday to Haejin..Happy Birthday to you.' Everyone clapped their hands, showing how thankful that she was born. Haejin blows off the candle after wishing in heart. She is so happy because it is her 4th birthday and she received a lot presents than last year. 'Haejin-ah..' Haejin heard a voice calling her name but she doesn't know who it is. She turns around and she saw a boy calling her. 'Oh Sehun!' Haejin ran towards Sehun happily seeing her best friend. 'I bought you a gift.' Sehun passed the present to Haejin. Her face turns bright when she saw a huge white teddy bear. 'Whoa! kamsahamnida.' She hugged the teddy bear, making her face hiding beneath it fur. 'You're not gonna forget me right?' Haejin shooked her head. 'Please don't forget me, arraseo?' Sehun hugs her and so she hugs him back.
