I broke the shark

[warped parcel]

Hi, I posted a question in the questions channel and it seems some other people are having the same issue as me!

The issue being that no matter what I do, after starting to date semeru he is hard stuck on 8 hearts. No amount of gifting or dating is moving it in the slightest. Any idea how to fix it?

I've reloaded the game and there's still no sign of any change on his hearts

God if i have to restart my game from the very start im gonna be crushed ;A;
