Loved/ taekook

helppppp

Guys i'm back and i need your help.

Last month I was reading a taekook book where tae and Kook are married and have a kid. But Kook kinda dies, but it is shown that Yoongi saved Kook and Kook is working under Min yoongi as Haechan whereas tae has no idea. He lives with his son and hyungs.

This is actually how much i remember. I dont remember the story name nor the Author's name. Nor have I added the book to my reading list. Guys please help me in knowing the books name.

I would be thankful if someone has read it and lets me know the story name.
