So there was this story I read years ago. It's not that I liked it very much but I can't remember it's name and the lack of knowledge has been bothering me for months now.
It's an office romance. Set in Australia. The guys name his Justin and last name starts with a T. So his colleagues call him JT. He is a good guy, friendly, popular in the office. His competer is a girl whose name I don't remember and they are competing for the same promotion. Whereas he is friendly, she is the ice queen but now that the promotion is in question, she has to act interested so she starts trying to interact with other colleagues but they're not welcoming. Also she is homeless due to some reason which is definitely not financial and has no friends and no place to stay So Justin helps her. Helps her make friends and let her move in as a roommate. Justin also has a history with an long time ex girlfriend named Sarah who lives in Sydney (that's where the promotion is for) and he wants to go there so that he can patch things up. The girl also had a boyfriend in high school who cheated on her with her best friend and hence the ice queen persona.
They're competing in the office but also living together and the romance happens.
[Spoiler :p]

She ends up pulling her application for promotion since she's in love with him.( She tells him after he gets promoted) He gets the promotion. They start dating long distance. He stays in Sydney for one year but stays away form Sarah. He gets back, they live happily ever after. That's it. I remember the whole fuckng story but not the name. Help!!!

I wish I knew what book this was so I could be of more help but it sounds pretty similar to "The Hating Game" by Sally Thorne. I haven't read it myself but I've heard good things!

Wattpaders! I need your help. I'm finding a book about this girl who was heartbroken because the guy she loved left her. I remember she have some guy friends who are really close to her and they protect her from Him(the guy who left Her) when He came back.
One of her friends has an apple farm, his name starts with letter B, I'm not sure if it was Brian or Bryce. Another guy friend likes her. I think there is a guy friend whose name is Ian, and then another guy I don't remember the name. She has a big sister, I think her name was Alex, but I'm not really sure. They don't have parents anymore.
When she was little, her father made a tree house(?) or maybe inside the tree, it was like her castle and she was the princess.
I remember a scene where one of her friend was brokenhearted and he went to her house and then she sang 'The Three Bear song' to comfort him.
Oh! I also remember that girl was sick, she's dying and all her friends got mad because she didn't tell them, only the guy friend who likes her knows because he's the one who help her keeping it a secret.
The main character guy was like a gangster or a mafia and he left her for her safety (2)
I don't remember the title and author but I still remember some scenes in the story. I hope someone also had read this story. Thank you in advance ♡

The book is "Winning at love" by Ellie fielding if anyone cares
