Stella?

I think he has a older sister and a young brother

Do you remember which chapter Stella was first mentioned in or was chapter 32 the first time she was mentioned? If you don't remember that's fine!!! Thanks for replying (⌒▽⌒)

She was first mentioned in one of the very first chapters when school just started and people were saying he’s the younger brother of her. It’s also said throughout the story a lot of times because in texts and a lot of other parts, his mom calls him the middle child

I checked again, it says it in chapter 2

Thank you so much for clearing that up for me!!!
