I went to open the door and saw mom ( mrs. Kim) on the door . Let me clear the confusion mom- dad means mrs. Kim- mr. Kim , appa- eomma means mr. Lee - mr. Lee.
Y/n- mom why are you here i can come to meet you if you said to me .
Mom- y/n i just wanted to know how my daughter is
Y/n - you should told me before i have picked you up.
Mom- no by the way where is that dumb

Y/n- no mom he is very caring. But yeah i get bored everytime.
Wth did she said .
Mom- tell me if he ignores you ok bye then .
Y/n- bye mom .
Y/n went to close the door and i again started to watch my show . I was waiting for y/n to come but that never happened. I turned  and saw y/n got a call . She started to talk . She looks quite happy. I went near to listen what she is talking about
Y/n- oh really, you are so funny. Yes i wish that too . Hmm i shouldn't have said yes . Then we should be together .
What .is she talking to her boyfriend. Oh so she regret marrying me . Yes you should regret. That's mean she was right. Y/n has a boyfriend. Just don't cross the line y/n.
Y/n- oh really i will try . Bye
I hided behind the wall . Y/n went in her room. I went to the room too
