both dramas are comedy focused and have some more absurd scenes and break the 4th wall sometimes. They also center around lgbt love stories and the endings are left rather open (YYY at least has been continued while Lily Fever seems to never get a follow up).
They both are GL and have a weird vibe to them. Yuri or Another isn't as confusing and also has a better storyline. They have a lot of weird but fun interactions and it has a lot more to it.
