my usual routine for each update:
-read chapter
-reread the cool parts or epic parts again
-reread the rimuru parts again
-stare at rimuru cute faces, and cute moments
-reread the whole update
-go back some chapters and check rimurus parts where he is awesome and cute
btw, the whole thing while smirking like a creep
setting aside that the protagonist became side charaters, they also became a carefree love-dovey idiot couple while everyone is having a hard time, well still love them a lot tho
