Because....Its Love!!

First string

7.00 P.M, Byun House

Mrs. Byun was knitting something with very much concentration by sitting on a tool in kitchen. Maybe that's why she didn't hear Mr. Byun calling her.
"Honey!!" This time Mr.Byun called her with a angry tone and entered into the kitchen." What r u doing??! I am calling u since a long time!! Can't u hear?!!"
"What?!! When did u call me?!" Mrs. Byun stopped knitting and looked at him with such a look as if he was falsely blaming her. "And if u did, then why? Can't u see I am doing such an important work now?!"
Mr. Byun got a little bit startled and started fumbling. "Ye-Yeah honey, I can see u r busy. Bu-But I just wanted to say that, I- I mean.."
Mrs.Byun left a sigh and again started knitting " If u don't have anything to say, then put the kettle on the stove. Ji Wook must be on his way. I have to keep the tea ready."
Mr.Byun at last remembered what he wanted to say." Honey, u have a visitor." Mrs.Byun looked up to him."Who?"
-"A girl from a boutique shop. She is saying u called her to deliver some products."
- "Oh yeah!" Mrs.Byun seemed to remember."I was lack of wools and laces as I was making a sweater for Ji Wook. See, isn't it beautiful?!" She showed the half knitted sweater to him excitedly,"My son will look too much handsome in this." 
Mr.Byun immediately nod."Of course" After that he added with a little pride, "After all he is my son. He had to look  handsome like his dad." Mrs. Byun put the sweater down and  looked at him with a sarcastic look." Don't blabber! I pray to god everyday that he didn't go over you!"
Mr.Byun coughed,"A-Ah! Okay, we will talk about it later. Now, meet that girl. She is waiting for quite a long time."
"Oh! Right." She kept the sweater on a bag after folding and came down to living room. A girl near twenty with short hair and elegant dress, was waiting there. She stood up after seeing Mrs. Byun and Nodded. "Annyeonghaseyo! I am Ji Hye, came from Sandy boutique. U have ordered some products. Here they are." She indicated to a paper bag in her hand.
"Yes, thank u so much for delivering them. I would go myself but I had hurt my leg yesterday. Sorry for bothering." Mrs.Byun said with a warm smile. "Oh no, its okay! Our pleasure." Ji Hye smiled back."We would have delivered it earlier, but our delivery girl had taken an early leave, so mom told me to bring it."
-Oh, I should have understood. U definitely don't look like a delivery girl. Really sorry for the inconvenience!''
-''No, no, its okay!"
-"Well, in that case, please join us for tea!" Mrs.Byun requested. "Oh no, its okay! Please don't bother. I am fine."
-"Yeah, u should join us. Our son must be on his way. He will also join us later. Meanwhile, we will be very happy if u have a cup of tea with us." Mr.Byun added.
-"Oh-Okay!" Ji Hye can't deny anymore. Mrs.Byun came back to the kitchen and started preparing for tea and snacks. Mr.Byun excused himself for a minute and went upper flore. Ji Hye was looking around the whole house. The house is quite big and well furnished. U can tell by taking a look that the owner is quite rich and has a good taste. She left a sigh. "Don't know when I will get to own such a house. Though mom always keep telling me to find a rich boy and get married. But the boys who r wealthy don't look good, and good looking boys r not wealthy."

She came back to sense by hearing a harsh sound of car parking. "Seems like Ji Wook has come." Mrs.Byun shouted from the kitchen. The sound of footsteps were coming close and stopped at the door. Ji Hye looked at the door a little bit nervously. The door handle started revolving......
