Only 52 chapters of this are translated, it was last updated in 2017 (2018? I'm not sure) I love how it starts as a harmless novel but then it becomes dark and.. i just love every bit of it. I'm very much interested to MC's older brother and his relationship with their younger sister but it's unfortunate this wasn't continued. It's Thai, i hope someone will pick this up.
