I always go to sleep hoping to never wake up again.

I rate dramas based on enjoyment and rewatch value. Generally, depressing stuff will be rated lower, regardless of its subjective quality or lack thereof.

For instance, a drama such as The First Frost is too depressing and somewhat triggering to me, so I do not dare give it a 10/10, even if I think it just might deserve it. On the other hand, something like "Love Me, Love My Voice" might not be as good [in theory], but it is very soothing to me, in spite of the lack of an intricate "plot".

Any drama with breakups [nothing like saying you love someone and abandoning them for stupid reasons], cheating [between the couples we are supposed to root for], or obnoxious love triangles [no love triangle whatsoever is ideal] also get lower scores, if I bother watching them at all.
