Rewriting My Tragic Ending

(Time of writing: Complete first season, 39/39)
I heard this was based on a novel and I can't find a translation, so I wouldn't be able to tell if the problems originates from it or not.
The best way to summarise this is a "a lore heavy tragedy that would rather be a slice of life". It keeps dumping tragic lore to you every other minutes and the plot has terrible pacing. I mean I can tell there's many great idea but the comic has no idea how to use them.
Scenes lack impacts because they don't give you any reasons to really care and it also gives the leads 0 chemistry. It just feels like one sided obsession on the ml part which could be a plot point but isn't. Actually the fl's dynamic with the sub-ml seemed more interesting and compelling.
Actually while the ml is pining, I kinda sat there thinking protag had better stuff to worry about than romance with some guy she met a few days ago.
Every element of an interesting mystery tragedy but amateur-ish writing, no character fleshing and rushing to put as much elements as possible in the first season.
I'll come back to see if it improves next season because, like I said, the elements are interesting, but rn this was a waste of time.
