Created by the same people, have a similar vibe - friendship, reverse harem, nostalgia, slice-of-life, coming of age. These are both dramas where you feel a connection to the characters and will always have a soft spot for the actors who played them. Both also have great soundtracks too.

Both include soul-swapping with unique storylines, well-developed characters, amazing chemistry between the leads, gorgeous visuals, and memorable soundtracks. If you are a fan of this genre, you must watch both all the way through. This includes Alchemy Pt 2.
