Although in Guardian the gay storyline is muted (in script, the visual language makes up for it heavily) Ossan's Love is similar in the aspect of the storyline revolving around the main character falling for another guy.

"Masquerade" with actor Lee Byung Hun in it, was the movie that inspired the Kdrama "The Crowned Clown".

I think that these stories have relatively the same premise: two art students meet in college and fall in love but then separate for one reason or another. They then meet again in the future. Art in Love is definitely a more light hearted approach to this concept, while Where the Lost Ones Go is a melodrama version.

They both are about teachers using 'unusual' methods to convey a message about society to their students. They give very similar feeling and even have some scenes that remind one another. Some themes are also common to both, as bullying, for example.

Its also about body switching, It is more dark and horror-ish but its also about friendship and love. It really touched my heart.

fair warning its dark and more serious.

Its similar with the body swapping but also very different ! You will love it for sure!

Its not only about body switching but it has such a cute feel too it
