Both "While You Were Sleeping" and "Lovely Runner" share a central theme involving the supernatural ability to foresee future events. In "While You Were Sleeping," the characters experience prophetic dreams that show future incidents, allowing them to attempt to prevent these events from happening. Similarly, "Lovely Runner" features characters who can travel back in time to alter events in an attempt to prevent future tragedies. As with "While You Were Sleeping," this creates a paradox: their actions in the past intended to change the future can either fail to prevent the event or cause it to happen in a different way. The very act of trying to change the future by modifying past events can lead to a fixed timeline where the future remains unchangeable despite their best efforts.
If you enjoy thought-provoking stories with engaging characters and intricate plotlines, both "While You Were Sleeping" and "Lovely Runner" are worth adding to your watchlist.

I mean beside the plot, the actors got the same haircut lol. I find it similar to each other as rival is same in age and more powerful than the protagonist.

Treasure hunting aka gold finding dramas seems such a rare in kdrama history, isn't it. As Vincenzo, EIA is also one of the funniest and most interesting drama in 2000s, but EIA clearly run for treasure hunting and friendship. They also have crazy and funny thugs. Give it a try <3

It should have to say Oppositely Attracted. Age difference between 2 series Leads are 10 years, only DIFFERENCE is Male side and Female side. Both are strong friendship based dramas. In GGS, it has plenty of bromance bond and in WWW, girlmance is on hand. Both are Strong friendship and Business dramas. If GGS is cute and funny, WWW is the way more sentimental.
