Hmmm idk how to feel abt this one

So like this is how the story goes in my eyes so far… my wakes up in his fav novel and all of a sudden is kidnapped, then he goes along with this master servant charade, gets harassed by ppl he his other world self knew previously, makes buddy buddy with keymaster and friends of ML, then falls in love/likes him but doesn’t know it. Then all of a sudden we’re dungeon diving and he decides to end his life to save ML and friends???? ML is like , boohoo for only 3 seconds and now we’ve gone back in time………. I feel like everything is spontaneous and the plot is not detailed. It’s confusing to me at least. With all the 5,000 chapters of raiding one dungeon and sudden character death. Open to opinions. Lmk if yall feel the same
