when friendship is raised and hearts are obtained.
Obtaining more than 10 hearts with a villager does not change the symbol that represents the friendship level, it remains as a purple circle instead of showing a purple star
When the friendship between me and Leo is lower than 6 hearts, he shouldn't become one of the villagers I send gifts to. Because he still lives in the Ginger Island and haven't moved into Stardew Valley, so I couldn't find him in the Pelican Town.
