After Himchan asked Haily about Korean she didn't know how would he reply if she told him that she learnt it by her own,,but she wasn't very good at expressing so she mumbled when she answered

Himchan:I'm getting out of here 

then he tries to leave but his father stops him

mr.kim: You are not going anywhere

Himchan:and why should i stay in here? To witness your cheating?

does mom mean anything to you?or what about me and noona?

mr.kim:I knew Jinny years before i met your mother 

and i told you everything before i bring your little sister here

Himchan:what little sister??I only have one sister ,only Noona and no other person

Haily:it's okay I know i'm not welcome here ... It was nice to meet you my biological father and mrs.kim

and Noona, i mean unni

And Channie I'm really sorry for making you feel this way

Himchan:what is she mumbling in English

Haily:you like cheeji burga??

Himchan:all of that mumbling for a cheese burger??

 mr.kim:you idiot you made her feel bad so she was apologizing and wants to leave

mrs.kim:what?? No dear stay here where will she go?

Noona:aah yah dongsaeng don't be like this to her she is your fan too

Himchan:what is wrong with you?? Can't you understand that she is the labour of cheating?

 Mrs.kim: don't you understand the  circumstances she is in??

Himchan:what are they?? Living in America with a nice family being a teenager and dating boys and spending mony like if she owns a bank??

mr.kim:she lived with a poor family and she used to work in the summer to get money 

her mother gave her to this family when she had blood cancer and then died

plus as her foster father says all house chors are on her and she treats her mother and father better than their own daughters

Himchan: I didn't know that
