This is the case of lovesickness. Yandere tendencies will occur. Toxicity is right around the corner. The mother is the worst. I want to kill her. Phobia is the worst. I hope Yul have someone to accompany and accept his weird gestures of love (The death rate aren't included) please add him to your baby cart
Maybe Ms. Mia disappeared or something. Is she abused on the real world?
So basically if you didn't read, she was abused and had no friends at all. She was all alone and yeah, then Ms Mia came upon her. She took her in and they played, had fun and all. Until one day, Ms Mia either died or disappeared (i dont really remember but yeah). Thats why shes asking "dont leave me" meaning don't leave her alone in the cruel world, where she was abused and only had her. Thats sad.
