Looking for a K-drama/Japanese series?
I'm not so sure anymore but I think it was a K-drama.
All I remember is that the boy lost his little sister back then (she was apparently kidnapped) and blamed himself for it. He's moving to a new town/village or back to his hometown. A girl he's met before lives across the street from him.
And I also know that the girl with her grandmother and mother (?) killed someone and put the body in the neighbor's refrigerator (the boy's)
(It was or is on Disney+ I think)
Eat, Love, Kill.
Runs on Disney Plus
They’re not siblings. But the daughter lives with her mother and grandma and killed someone and put in the disassembled fridge that was put back in the end by the employees. However, the two have the same telepathic abilities, but the girl is not the sister of the boy.
Thank you, this is the one!^I know that the girl is not his sister. I might have put something wrong
