please help

I’m looking for a book i read some time ago so it’s not newly released. I don’t remember a lot just that it was grumpy-sunshine, fmc was taking care of her sisters daughters (if i remember correctly) and one of them played soccer, maybe something else but she was playing some sport and fmc was taking her to practices, it was small town romance and i think the mmc was a coach of kids team. MMC didn’t like FMC at first. He was grumpy and brooding and i think they had some fight and he apologised in the parking lot after some game and her kids helped him. That’s all i remember maybe someone can help me😩
