Help me find this webtoon

it’s a very eerie webtoon chapter about a little girl writing in a notebook. okay so, i remember first seeing it on a tiktok slide show somewhere in 2020-2022. it’s a korean story because thanksgiving is in october. it was a little girl writing it her school notebook, and there was a box for drawing a picture. it was very eerie and all signs lead to the dad being abusive, i remember she said she got a dog and it’s name was bubbles? she drew it very human like even drew it crying once, people said it’s actually her brother and her dad made him act like a dog for wetting the bed. i remember the teacher would write on the pages too. and one day the little girl just stopped writing. this was like a different type of chapter in the webtoon. i went to r/webtoon and have had no luck… please tell me someone knows what i’m talking about ?
