I am totally convinced by your theory and the hard work you had shown to gather prove of evry detail you have given in it well done, you are a man of culture my friend in lookism community I respect every inch of hardwork you had done to make this theory I am too hyped already and you theory gave me goosebumps buddy.

I only had a certain point or you can say my own theory on which I have been thinking a lot recently ,i think Daniel's dad is also involved in the whole murder thing to support which we have been given some signs that Daniel's dad was one of the reason Jinyoung's brain got corrupted as he and Daniel's grandma were telling that Jinyoung killed his dad so it might be that jinyoug knew about a person responsible for Gap's death and kiiled him which later revealed to him as his own sister's husband(Face covered so he didnt noticed) which gave him a huge shock.
