We're going fishing tomorrow.
I want to go now.
- You want to go fishing? / - Yes.
(Seungjae has transformed. He whines more.)
Hey, you have to speak nicely.
(Upset)
What happened to our lovely Seungjae?
The camera is telling me not to cry.
- Yes. / - I won't cry, camera.
(Seungjae has transformed. His mood fluctuates.)
I'm sorry for crying.
(Feeling dumbfounded)
- Are you petting the camera? / - Yes.
- You're sorry? / - Yes.
I answered the phone.
- You answered the phone? / - Yes.
I called Mom with the phone upstairs.
What did she say?
(Seungjae has transformed. He bluffs more.)
She said she'll be back soon.
When did you speak to her?
After I woke up.
- You called her after you woke up? / - Yes.
(Confidently exclaiming)
You're lying.
Seungjae, you're lying, right?
- Yes. / - Right?
Why are you such a liar now? You lie so much.
Who's a liar?
You, Seungjae.
You're the liar.
Why am I the liar?
Seungjae, who taught you how to lie?
You. I learned from you, Dad.
- You learned from me? / - Yes.
(They attempt to interview the cranky boy.)
(However...)
Did you go to school, Seungjae?
(He refuses to hold the interview.)
Are you upset these days?
(Kicking)
Are you upset?
(Even his gaze is rebellious.)
Hello.
How old are you?
(He used to be such a well-behaved baby.)
I don't like you. Go away.
Why don't you like me? Do you want to be alone?
Yes.
Why are you upset?
I don't want to do this with you.
You don't want to do this?
No. I said I don't want to say bye.
Then should I come visit often?
No.
- No? / - You can't. I want to play alone.
I'm upset.
(Has our lovely Seungjae transformed?)
Seeing that Seungjae is not his usual self,
Jiyong decided to call someone.
- Hello? / - Hello?
- Hello there. / - Yes, hello there.
It's me, Seungjae's father. Have you been well?
Of course. I'm busy as usual.
(She provided valuable assistance)
(to Jiyong, who struggled to feed Seungjae.)
- Try it. / - All right.
Hands up.
This is Mrs. Oh,
an infant care mentor.
Seungjae must've grown up a lot now.
Yes, he did grow a lot,
but it came with some side effects these days.
His behavior is a bit off.
- He gets cross easily. / - I see.
He throws tantrums often as well.
I see. Does he whine a lot, too?
Yes, that's correct.
His whining has gotten pretty bad.
You might not understand when I say this now, but
- Hold on. / - have you heard of "infantile puberty"?
- Did you say "puberty"? / - That's right.
He's four-years-old. Is puberty even possible?
Just like how teenagers undergo puberty,
it's another developmental stage of growth.
That's what I mean by "puberty".
I see.
By now, he probably has many interests
and makes more demands.
But many of those things are impossible,
so it frustrates him.
Continual disappointment can cause the child
to whine more frequently.
Playing is a great solution.
Especially for children who like to role-play,
it'll be very helpful if the father can pretend
to be the child's age and play along.
Thank you for your advice.
She called it "infantile puberty".
I thought about various methods to deal with it.
Then I remembered Hwijae
pretending to shrink himself.
(They even sang for their father.)
Dance.
(Prancing about)
I'd wanted to try it too, when Sooin doesn't behave.
Dad.
Dad has gotten so short.
(It motivates the children to declare good behavior.)
This is his colleagues' secret education method,
the "Daddy has shrunk" technique.
Will the method work on Seungjae?
(Seungjae scurries outside.)
(A strange feeling pervades the living room.)
Where are you hiding, Daddy?
Seungjae.
Ko Seungjae.
(Jiyong has disappeared.)
(Only a figure that bears his resemblance stands.)
(How will Seungjae react to the figurine?)
Seungjae.
(Crying)
Come over here.
Dad.
(Jiyong finds the situation amusing.)
(Seungjae carefully approaches.)
(Is this really Dad?)
It's Dad.
Show me how small I've become with a mirror.
(A mirror?)
(Staring at the mirror)
(Seungjae peers into his own reflection.)
I don't see you, Dad.
(Goodness, son.)
I don't see you, Dad.
I want you to show me my reflection.
I want to see how small I've become.
Make sure I can see it.
- Gosh. This is me? / - Yes.
- I've gotten this small? / - Yes.
Seungjae, if you behave and take care of me,
I can go back to being big again.
- Can you help me? / - Yes.
- You're like a big brother, right? / - Yes.
(He wipes his nose like an older brother should.)
I'm going to wiggle my fingers over you.
I couldn't hear him. What did he say?
Are you trying to do magic, Seungjae?
Yes.
Abracadabra, make Dad big again.
(Silence)
Seungjae, that's not going to work.
(I want to make Dad bigger.)
Dad, where is your food?
What will Dad eat?
(What kind of food is Seungjae looking for?)
Dad.
I'm going to feed Dad cheese.
(He brings cheese full of calcium that helps you grow.)
(He unwraps the slice of cheese)
(and gives him a small bite.)
Dad won't eat.
(He is sharp.)
I can't eat since my mouth turned small.
(In that case, I will eat it.)
Seungjae, why are you eating it?
Your mouth turned small.
You need to cut it into a small piece.
Hold it to my mouth.
I will melt it.
(Laughing)
It's tasty, Seungjae.
Seungjae, I'm bored. Sing me a song.
(If that's what you want.)
(One elephant)
(It's a familiar song.)
(When Seungjae went hiking with his dad,)
(they sang the song together.)
(My dad used to be big.)
(I can't believe this.)
Sing louder.
(They merrily went on swinging)
(Even though he is sad, he follows his dad's wish.)
Louder.
(He finished singing the song.)
Seungjae suppressed his sadness for his dad.
It's so touching.
Seungjae, would you take me out for some fresh air?
Yes.
Since I turned small, you have to get dressed alone.
(He attempts to get dressed alone.)
- These? / - Yes, change into shorts.
(He takes off his indoor shorts.)
(He puts them in the laundry basket.)
He didn't have to put them in the laundry basket.
(He pulls up his shorts.)
I am done.
Change into a yellow T-shirt.
Dad, I won't be able to do it.
Dad, I can't do this.
You can do it.
Uncle, how do I put this on?
Here.
Like this?
There you go.
Good job. You should put on your socks now.
(Staring)
(He suddenly picked up his small dad.)
(Did he notice something strange?)
(Hugging)
(He puts his dad against his chest.)
(He holds his dad close to him.)
Dad, wait here.
I should check your temperature.
Your ears turned so small.
Should I give it a go?
(He checks if his dad is sick.)
30, 550 degrees.
(Leaving)
(Seungjae...)
Uncle.
Look at this.
(He wears his socks in front of a cameraman.)
Wait, I should bring Dad.
I should bring Dad.
I should bring Dad.
I forgot to bring Dad.
I had forgotten to bring you, Dad.
Thank you for looking after me.
(Don't mention it.)
(My goodness.)
Oh, no. Did the doll's arm break?
How will Seungjae react to this unexpected situation?
Seungjae.
(He tries to put the arm back.)
My arm broke.
It's okay. It's okay.
It's okay. It's okay.
Seungjae, what do I do?
Don't cry. Don't cry.
Don't cry.
