Even though the plots are different, both stories take place on a college campus. The characters of the respective dramas get to know each other in a natural way and become lovers that break-up. In the end, they do get back together--a happy ending. Most of all, both stories depict the growing pains of young adults and how these experiences and people form their identities.
Where the Lost Ones Go is very similar to Unrequited Love in terms of plot and storyline. Although I did think WTLOG was more satisfying, it gives the same nostalgic vibe that makes both dramas so enjoyable to watch.
