Now I make some wild guessing. Ready? Go!
- You didn't read the book of super photographer before the photo shoots with Emily
- Because you didn't read that, the photo shoots weren't success
- Because they weren't succes you couldn't buy the Harley and Ninja cosplay from the store
- Because you couldn't buy them, you didn't do the 3rd and 4th photo shoot with Emily
- Because you didn't do them, you didn't do the photo shoot with roommate, nor the one in the living room, neither the other one in the bedroom
- Because you didn't do the second photo shoot with her, you are stucked with 1 heart.
- Also you'll stuck forever with Bring Anna home task. :/
But just for you to see, this is your relationship with roommate:
As you can see, if it weren't the limit you could have 6 heart with her already, so the hearts not the problem.
