I don't see any major issues with this drama. It's simple, sweet, and maybe slightly corny. All those annoying cliches? Basically, thrown out the windows. You see these four (five) characters grow together through high school to university. Nothing too complex; it's been done so many times before.

I was so glad this drama did not try the "A Love So Beautiful" approach. I can't stand love triangles, especially one in a friend group.

The two downsides? The romance was very weak. Sure, not every romance has to be passionate or even interesting, but at least make the story around the romance interesting. It wasn't. The second thing is the story, clearly. It was boring. But at least I didn't feel frustration over the characters. I just felt... nothing. When I got to episode 20, I was so ready to stop. I pushed quite hard to actually finish this. It just wasn't interesting. Not even the romance can save it—it's part of the bore.

It's funny they moved in together because they even kissed. I think they skipped a step there.
