I have developed quite the affection for uplifting, upbeat, lighthearted animes like this one. While the MC DOES have a BIT of the OP-ness typical in anime, she is NOT some kind of "destined, Chosen One" or anything. She is just a young person to whom Fate has dealt a "bad hand" and is trying to change her misfortune though hard work & learning "who" she is as a person. A very "feel-good" anime IMO.
After selecting 480p, rewind the video to the beginning, and you can watch it normally.
