"What do you mean missing?"
        "We try to go to her home and to call her, but failed," explained Jaehwan, "do you know how to contact her, Hakyeon?"
        At this time, I feel failed as her boyfriend. I know nothing about her. Even I don't know where her parents are now living. All I know is she is living alone in Seoul, while her parents are quite far now. I'm shaking my head.
        "I guess we should use Taekwoon hyong's idea, that we should find out about her from the university," said Sanghyuk, "if we say it's urgent, maybe the university could tell us."
        "Maybe she is just going back to her hometown?" I asked, even though I'm not really sure about that too.
        To be honest, I'm not feeling good towards her lately. I need to talk with her. I really need to. I got my phone and call her, but her phone isn't active.
        "The one that we worry about is her health, Hakyeon," said Taekwoon, "Hongbin said she was fainted after came back from your apartment around a week ago. And her appearance is looks like she is sick or what."
        "Yes. That's why Hongbin suggested her to have medical check-up, but we never saw her anymore since the last Hongbin saw her," explained Wonshik, "what should we do?"
        "Let's gather information about her," suggest Hongbin.
        "What can I do to help you guys?" asked me, feel useless.
        "Only one, I guess. Try to call her, who knows her phone is turn on, then talk to her," answered Jaehwan, "and leave the rest to us."
