Gold Land

Same plot device here. FL receives goods (gold/dregs - I'm on school laptop) and becomes obsessed. FL in WOTI was also the center of chaos with police detectives, and dealers. They are pretty much the same thing, besides the certain goods.

Both of the main characters are poor and get greedy once they were able to get rich . Both have suspense.

Both are crime related dramas with the main leads caught up in criminal activities introduced by another party
