Jungkook always have been a soft hearted and innocent person, he has no kind of evilness in him and especially in times like this when he knows his wife was struggling with life and death inside he OT, his heart was breaking more and more..
Your blood type was O- and needed blood urgently but none's blood group matched with with yours except one person..jungkook.He already was so much distressed and couldn't understand this whole situation until the doctor explained to him that this is the matter of life and death
He sat quietly as if thinking something and then bid goodbye to everyone,none understood his actions until they took his blood and he asked
"When will I die?" he asked innocently thinking the doctors were giving his life for yours but in actual they weren't, they just needed his blood..the thing which made everyone's heart melt was he thought he'd die to save you and was actually fine with it
