Strict dada of taekook

Chapter #2

I forgot to mention that Taehyung is 5 minutes younger than Jungkook .
Jimin went to the hospital. Kids were preparing for exams which was going to be held from the next week .
Jungkook quickly wiped his tears , took a deep breath and went to open the door.
Tae : Jungkook?? Is waiting for you in the living room .
Jungkook : I'm not coming.
Tae : kook try to understand at the end of the day you had to meet her as she gave you and me birth . This is the fact which no one can deny . ,( softly )
( Taekook bond wasn't just hate but it was love hate bond instead. They both shared precious moments together and cherished themselves. But sometimes taehyung says hurtful things to jk ) .
Jungkook: ok you go I'm coming.
( He went to restroom, washed his face , wiped the water then went downstairs)
?? : how are you baby ?
Jungkook: You can see miss eunji .
Tae : Is this the way to talk to your mom? ( Stren )
(Jungkook didn't say anything)
Eunji : I always say you to clear your misunderstanding .
Jungkook: Which misunderstanding?
Eunji : I'm pretty sure that you misunderstood something that's why you always behave with me like this .
Jungkook: You left my dad . Is this misconceptions? ( Rudely)
Eunji: I'm going. Take care both of you. 
( She left . Taehyung see her off and shut the door then turned around with dark red eyes which seems furious.  Jungkook was going to upstairs)
Taehyung: STOP RIGHT THERE .
Jungkook: W-hat ? Why are shouting ?
Taehyung : WAS IS THE WAY TO TALK TOUR YOUR MOTHER, YOUR BLOOD?
Jungkook: Then how should I talk to her ? Because of her we are suffering. Our emotional needs are not being met . No doubt Appa tried his best to express his love and affection. But he is doctor he spends most of the time in the hospital.
Taehyung: STILL JUNGKOOK YOU CAN'T MISBEHAVE WITH YOU MOM . DON'T YOU KNOW HOW MUCH PAIN SHE WENT THROUGH WHILE GIVING BIRTH TO YOU AND ME ? HOW MANY NIGHTS SHE HAVEN'T SLEPT DURING YOUR EARLY YEARS ? DON'T YOU SHE ALWAYS PRIORITISE US ABOVE HER WISHES ? SHE DID THIS JUST TO SEE HER KID MISBEHAVING WITH HER.
Jungkook: ENOUGH! If she priorities us then we would've been like this. She is your mom not mine . You are such a bitch ( cut off )
On the other side jimin came in his cabin after surgery. He was so gloomy. Whenever he saw any happy and cute couple his memories hit him like strom. Just like today he saw a boy crying and love moments with a girl who is going to an operation theater . 
Jimin : Why didn't you left me ? Wasn't I good enough?
( Feeling like you're not good enough is a common struggle that many people face. It's that nagging voice in your head )
Jimin : I can feel the sensation the be loved and cared by their own mom in the eyes of our kids.  Haven't you think about them before leaving us .
( He took a deep sigh , picked up key of car , went to parking area , open the door of car , sat in , then went back to the house )
He came back and the scene Infront of him made him thunderstruck. After a few seconds he went to them and make them separate.
Jimin : WHAT ARE YOU BOTH DOING? HAVE YOU JUST RAN AWAY FROM MENTAL CHAMBER? HUH
Taekook: A_appa ( gulped )
Jimin : I'm just going to freshen up I want you to in my room's corner.
Taekook: Appa sorry . It won't happen.
Jimin : SHUT UP BOTH OF YOU . I DON'T WANT TO HEAR A SINGLE WORD FROM YOUR MOUTHS.

Suddenly the kook began breathing heavily.

Tell me which punishment should jimin gives ? What were they doing when Jimin caught them?
