I wouldn't say that this was a bad show. The acting is fine, so is the music and the story is also good enough that I didn't feel like I was activly loosing braincells while watching.

But I think what this show struggles with the most is that it doesn't seem to know what it wants to be.
The intro (looking past how ugly it is, seriously who thought this was a good idea) suggests to me a fairly lighthearted goofy show. But then the first episode has three suicide attempts and then MC has PTSD. And these are treated seriously.
But then we also have more comedic parts. More plot heavy stuff and even some detective things.

Instead of committing to one thing it seems that the show tries to be everything at once and therefore struggles to be anything at all.

That being said I can still see how some people would enjoy this drama but it's not for me and I probably won't continue it.
