This is definitely going to go down as one of my favorites. There's something really wholesome and heart-warming about the entire plot, and even though the problems that the characters face are sometimes really intense, I don't think the vibe of the overall drama ever wavered.

Shut Up Flower Boy Band is surprisingly realistic, and one thing i really liked was that there wasn't one evil antagonist they were all going up against—most of the conflicts were internal struggles or tensions with friendship, and the show handled it all really well. Even the characters who didn't really get along with the main characters were very three-dimensional.

Even though there were some noble idiocy plot points, which I usually hate, I liked them in this show and I understood, mainly because even though the characters were fighting, it never felt like they were no longer friends. The bromance was one of the strongest parts of the entire show and I loved the way they handled conflicts with one another.

Su-Ah and Ji-Hyuk were super cute together as well—after I finished watching the drama, I went back and rewatched all their scenes together. I also liked how there weren't a lot of needless misunderstandings between them; even though they found it hard to talk about their feelings sometimes, when it came to it, they really understood each other's choices. Ji-Hyuk was kind of a bad boy but also lowkey always soft for Su-Ah, which was adorable. Su-Ah was a surprisingly strong female character who spoke her mind a lot and stood up to others, even though she is quiet—but I do wish they had given her even more regarding her art. While the guys had their music thing going on, it felt like her artistic talent was hinted at but it never moved forwards. I wish we saw more of Ji Hyuk's family background too, as it was pretty much only hinted at throughout the drama and I think could've played a bigger part.

Hyun-Soo (L from Infinite) was also one of my favorite characters, who was given a deeper personality than the others. I wish we got to see more of his interactions with his sister. His romantic plotline, though, was something I had mixed feelings about—and I'm not sure I'm fully on board with the ship.

Overall, though, I don't think I was ever really annoyed with ANY of the characters, which is a rare occurrence for me.

I did get spoiled for The Catalyst Event at the end of episode 2, so honestly I didn't find that as heart-wrenching as all the struggles that the characters had to go through afterwards.

I love the OST too—especially Jaywalking and Wake Up, of course—but I'm not sure I love the soundtrack as much as I loved Heartstrings'.
