Kairos have the same concept as this but instead of a walkie talkie the transmission is thru a modern cellphone and it always transmit every night for 1 minute (I forgot what time it is, probably 11:45), ML from the future and FL from the past, the plot revolves around finding the daughter of the ML
I just recently finished the s1, the new addition of character in the main lead criteria is revealed so he's probably the new holder of the walkie talkie from the future
the ending is a cliffhanger, and I'm afraid that they will probably introduce an another character who will be on other side of the walkie talkie, they'll be the one on the past while the other side is from the future, it's already hinted in the very last part of ep 16
I hope this becomes a lesson for the writers. They should have stuck to the slice-of-life/family genre instead of inserting that love triangle, which was poorly written and unpleasant to watch. The kid already hyped the show, so what was their goal with that storyline? The ending of the love triangle was generic anyway. What a waste of episodes. They should have just rushed that part and created a more intriguing plot or story for the remaining episodes.
One of the thing that I hate in kdrama are first they will make us hate a character badly(for eg in this kdrama…
I'm also beginning to believe that all those shinenegens that the fl is doing is for the sake of lengthening the drama lol, I want woo jo to have more screentime and bonding
