Jungkook had just got his brand new iPhone after two weeks of begging his umma. He wanted to start using it immediately but he had no idea how to use it. So he decided to ask his best buddy, Sehun. "Hey hyung, I just got my new iPhone," Jungkook said. "Really? But I bet you don't really know how to use it right? Anyway, meet you later at my house." Jungkook learned all the basics and he was really happy. On that midnight, he received a message from an unknown person : you shouldn't have bought this phone.

     Jungkook went to school early the next morning. He had talk to Sehun about the message he had received yesterday. "Hey hyung!" Jungkook called out when he saw Sehun. "Yes, dongsaeng? Wow, this is the first time you are early to school," Sehun said. "Hyung, can you have a look at this?" Jungkook showed Sehun the message. "Hmm...maybe this is prank, or the sender sent it wrongly, let me have a look at the phone number," Sehun said. He looked closer at the screen. "012...345...6789, no, I don't know anybody with this phone number. I think that this is probably a prank. Just don't think too much about it, kay?" "Ok, hyung." Jungkook said, feeling relieved that it is just a prank. Ping! (That is Jungkook's phone notification sound.) He read the message," this is NOT a prank. this is meant for YOU, JEON J
