This season was by far the best plot-wise! The story line was more interesting than the previous seasons, and the pacing was just perfect.

I guess one reason to this was adding Kim Saeron's new character. We have been so used to the fixed casts and regular couples Hyun Seung and Jiwon, Jun Mo and Doyoung that adding her made us curious as to what this new character's role was that it brought us something new to look forward to. I had my doubts at first, but adding her character together with quiet guy Ha Neul was really cute. Who knew he could be someone so cool and romantic? He was the shy and quiet best friend with Pu Reum but now he's definitely strong lead material with Ji Min, and because of this i'm already looking forward to a Season 5 with them as the main story!!

We also see the character development for the casts this season as they experience challenges to their friendship with the issue of military enlistment, and graduation, and how they stayed strong for each other and kept in touch despite being apart. Despite all the goofiness, they are there for each other no matter what. Its also nice to see how they welcome new people into their circle despite not knowing them fully with Pureum, Haneul, and Jimin, it just shows how good and reliable of a friend and sunbae they are.

Something about Love Playlist 4 just made me feel all warm and nice after finishing it. How I wish I could have friends like them where I can be myself and goof around being too conscious about being judged.
