because people have more time to watch youtube videos on the weekends, the weekends have higher viewgrowth in general than the weekdays.
All of Marine's songs also have higher viewsgrowth on the weekends.
If you want to compare Marine to that Ui graph, you should look at the Bishopai or Maribako or something that released a while ago to compare what the mature decay patterns are like.
e.g. here's Bishopai over the same period as that Ui graph, looks very similar because they're both popular songs that released around a similar time so they're both in similar phases of their growth trajectory
