Jihyo slightly kicks JongKook's leg under the table like telling him not to joke around like that when he knows she is already has a boyfriend.

SukJin: Yah Jihyo ah, you heard what JongKook said. Go out with him sometimes!

Jihyo: JongKook oppa is only an oppa to me dad. Stop expecting more.

Then she is using her chopsticks to picks up a piece of meat when suddenly she feel like vomit when she puts it close to , SukJin and KwangSoo worriedly asking if she is feeling ok, she replies that the meat smells bad that she can't eat it. SukJin surprisedly saying that he choose the best piece from the market to make it for her, he tries the piece himself and it is tastes good, KwangSoo also tries one. 

Jihyo: Then why only me can't eat it? (she tries it again and she feels like vomit too this time)

JongKook is thinking to himself for a second then he realized something about her, he slightly pushes on Jihyo's arm with his arm like he is warning her for something. Jihyo looks at JongKook like she doesn't know what he wants then JongKook quickly changed the topic to something else before SukJin and KwangSoo asked she more about it. After the dinner SukJin also prepared the dessert, Jihyo excitedly picks up a piece of watermelon from the plate and JongKook stopped her immediately by saying she ate too much already and now she is eating again, she doesn't remember she is on diet anymore. Quickly gets the idea that Jihyo also thanking him for stopped her that she forget her diet plan, KwangSoo jokingly saying that she is 58kg already which any diet plan wouldn't work on her. Jihyo stands up and hits his head from the other side of the table, leaving everyone in laugh, that is how they called it a night. Jihyo walks JongKook to the door,

Jihyo: Oppa, thanks for keep an eye on me when I was so reckless!

JongKook: No problem, but be more careful later.

Jihyo: Alasso!

JongKook: Jihyo ah, when are you plan to let them know about your baby? Your bellly can't hide any longer.

Jihyo: I'm still looking for the right timing, gomawo oppa for being so thoughtful about me all the time.

JongKook: You better go back inside, the air is chilling tonight!

Jihyo: I will after you leave.

But something they don't know that SukJin isn't too far from there, he was supposed to give JongKook some packed foods so he could eat it later. He accidentially overheard what those two are saying, his fist is squeezing hard and quietly he walks back inside. Jihyo is coming back inside after she sent JongKook off, seeing SukJin is sitting himself in the livingroom without the tv on unlike the usual.

Jihyo: Appa, you don't take some rest? It's pretty late already.

SukJin: Jihyo ah, come here. I need to talk to you. (really serious tone)

Without knowing what is going to happen Jihyo obediently walks over and seats herself down in front of him. Jihyo knows then there is something serious because SukJin is looking mad right now.

Jihyo: Appa, what do you want to ask me about? (timidly voice)

SukJin: Who is the father of the baby? (angry voice)

Jihyo's heart immediately dropped when she hear his words like how did he found out about her pregnancy, but she is trying hard to put on an act and keeps calm.

Jihyo: Father....of the baby??? Who is the father of the baby???? What are you talking about appa??? (stays as calm as she can)

SukJin: I AM ASKING YOU ABOUT THE BABY INSIDE YOUR BELLY, WHO IS THE FATHER OF THE BABY???? (he hit hard on the coffee table, jumps up from his seat, pointing and screaming at Jihyo)

Jihyo's hands start to shiver and she bites her lower lip hard, she still doesn't know how to answer his question.

Jihyo: Appa....(she is scared) Mianne, I did you wrong...(crying and avoiding the eyes contact) Please let me explain.....

SukJin: SONG JIHYO, YOU DISAPPOINTED ME!!!! YOU KNOW HOW MUCH HOPE I PUT ON YOU, YOU GOT EDUCATED WELL FOR SO MANY YEARS AND STILL MADE THAT KIND OF FOOLISH MISTAKE? YOU BRING SHAME TO MY FAMILY, I REALLY CAN'T BELIEVED TO HAVE A DAUGHTER LIKE YOU. (heartbroken)

Jihyo: Appa, I am really sorry..! (crying harder)

He fell down to the couch and crying, blaming Jihyo for what she did, Jihyo immediatly kneels down in front of SukJin and begs for his forgiveness. KwangSoo who hears the noise, quickly get downstairs and seeing some mess is happening in front of him. He comes over and asked for what is happening. SukJin again raised his voice, points at Jihyo and tells KwangSoo that his sister is pregnant in sorrowfully. KwangSoo get shocked by the news she is pregnant, eventhough he knows she is dating Gary but this stage just happened too fast between them. KwangSoo runs over to Jihyo and asked if this is true, Jihyo is only crying without telling him anything but that is enough for him to comfirms the truth. KwangSoo's legs gone weak and he fell to the floor, his jaw drop
