Encountering of pretty, but mysterious girl

Tyler was gone! Sung-min and Lucas have no idea where he disappeared from this small room. Both are running and worrying about Tyler. Unexpectedly Sung-min fell into the basement, Lucas followed him and both discovered underground basement hiding behind LOL.

"This seems secret agency working on something. I'm sure Tyler is somewhere around here only." Lucas said. Both were soon observed by security guards and everyone started running after them. They both locked themselves in a small room. When Sung-min turns he notices a brown girl crying in corner, she is unevenly wrapped in just a long piece of cloth. "Pretty" Sung-min blushes. Lucas finds the map of laboratory and shouts, "Hurry Sung-min! I found the way." Sung-min starts running then the girl falls in his feet, asking for help.

Lucas is out of the laboratory. Sung-min is out too with the girl in his arms. They hurry to Lucas' car and leave that place. The girl is sleepy and resting her head on Sung-min' shoulder. They took her at Sung-min' house because his parents were in Korea. "Who are you? What were you doing there? What is the aim of that secret agency?" Lucas asked to the girl. She is nervy and didn't say a word. Sung-min handled her his comfy clothes and said, "Wear these, you don't seem comfortable in this draped cloth." The girl is now feeling easy and secured after changing. Lucas asked again rigorously, "Will you please tell us about yourself and that agency?". In order to console frightened, sad girl he said, "You must be hungry. Let me quickly prepare ramen for you and Lucas, please come here for a bit." Lucas annoyingly followed him in the kitchen and asked, "What is your fucking problem man?! We have already lost Tyler somewhere and now you are babysitting this weird girl, who don't have presence of mind to answer my questions!" "She is just panicked and weak, not even able to walk properly. She must be knowing something about the agency and surely help us to find Tyler." Sung-min tries to save the girl from temper of Lucas. "Fine. I'll give you time to communicate with her, but till tomorrow evening if you won't be successful in collecting information from her, I'll straight away call police and take this case on upper level." Lucas is intimidating Sung-min without knowing the girl can easily listen their conversation even from a far room. The girl have dinner and Sung-min arranges room for her to sleep. "If you need anything feel free to ask, I'm in the next room only." Sung-min tells this and turns to leave. "Sung-min!" girl stops him and says, "I'm Parvathy." Sung-min was delighted to see her interacting. "Good night Parvathy!" he smiles and leaves. Sung-min says this to Lucas who was drinking in the hall. Both notices that Parvathy 's room closed by itself but ignores assuming that this is just their hallucination. In the room Parvathy takes out a string of prayer beads from her bag which she brought with her and starts chanting something which makes her a bit anxious. At around 3 am she is roaming all around and talking to someone.
