The gift wasn't the memory loss but a wish, and the wish was made by (I forgot his name sorry) for the other to lose his memories because he thought as long as they were together it'd do no good for the other because of something that happened the other season which I forgot what it was
Sorry I couldn't be of much help, just a bit of context

So season 2 of red string is kihoon losing his memories. I don't get the whole memory loss plot. The description of the red string season 1 was to believe in destiny and be with your destiny to get rid of kihoons misfortune but the description for season 2 was a "gift" From to rock. How is the memory loss a gift and why is it that only one of them loses memories. Pls ive reread this story so many times and still don't get it
