What kdrama do you wish you could erase your memory just to watch again

There are so many dramas I wish I could watch again for the first time just because they are that good! But mine definitely it alchemy of souls(both seasons was amazing to me), my demon, sweet home especially season 1, doom at your service, it’s okay not to be okay, Vicenzo, love next door, lovely runner and twinkling watermelon. I know all this are on the popular side but I like to think they are popular for a reason and I just love them. I’m curious on what other people think so ,What are yours?
