when jungkook got injured he made sure to take care of him, making little jokes to make jungkook smile and feel better
jin grabbing jk's hands to slips a hot pack into it because jk was feeling cold

since the beginning seokjin knows that jungkook tend to be shy and introvert when it comes to talk to the cameras, but he always made sure to focus the attention on jungkook while making sure jungkook knew all of them were there for him
seokjin never got his eyes away from jungkook while they were performing, to make sure he were okay and smiling all the time
even before he opened the door seokjin already knew it was jungkook and he opened with the biggest hug while happily said "jk!"... and jungkook's jin-hyung smile at the end

i mean, seokjin always knows that jungkook is the one who will opened the door... they have soulmate sense
he even made sure to clean jk's forehead for him since he couldn't do it by himself
he just can't hide his smile when he looks at jungkook
"i haven't had this luck for a long time" when they ended being in a team together... look at jin's big smile
seokjin who in multiples times have said that he hates when people touch his face was batting jungkook's hand away but inmediately calmed down when jungkook softly said "jin my hand, my hand"... jk is the exception

he is always the happiest for being in the same team as jungkook
seokjin even stopped his live since he wanted to see jungkook because he missed him...
"... i like jungkook the most..."
seokjin always calls jungkook "jk-ah, my pretty boy, honey, oongguk-ah, baby"

seokjin literally threw himself backwards without hesitance or any fear bc he knew jungkook was there to catch him without fail... he trust and loves jk so much

~the end~
