Seeing her so happy made me feel happy.

You could see how happy she was when voted least unhygienic and least lazy. Then when it came to most interesting housemate, she hadn't won one yet and said "hope this is me, I like this one", so cute. She won and could see just how happy she was.
We also saw her be happy for her friend Christopher when he got least false (something a lot of haters will have completely ignored just like they ignored everything else positive about their friendship)

Then when BB said you must all keep your boards on, she said "okay!" in happy voice

After when she chatting with Winston, she was funny and adorable saying "I got 3, I'm gonna write on my board least hygienic and least lazy"

Then later on when BB said all housemates can now remove their boards, she was thinking "I like mine, I don't want to remove it".
