Season 4: A bloated mess. Shoving a handful of too many characters and stories in a small package that couldn't accommodate for the change, making the whole thing out of focus and disorganized. It also failed in adding anything substantial to the original Love Playlist plotlines. Only "Han Jae In" was semi-relevant in that regard, even then, her story fell quite short. I guess they wanted to take it into a new direction without making a reboot but didn't know what to do with the original cast members.
