“Hello my angelic pretty nuna.” You let out chuckle from the word that came from your little brother mouth. “You need money?” you know Byungchul is pouting now taken aback with your question. “Yah! Nuna, am I that kind of dongsaeng?” “Nuna can’t even tease Byungie now? Nuna is so sad Byungie.” You reply with a fake sad voice. “Arasso, Nuna. I just want to tell you. I’ve won the best student award for this semester.” He said smiling. “Congratulation, dongsaeng ah” I said with excitement. Byungchul has always been the smart type. You know you don’t have to worry about him.
