It's creepy and really freaking eerie...but it's something you can't put down. I'm drawn to the mystery as well as the beautiful artwork. This story is about two siblings, Lilian and William who were separated when their parents passed. After many years, they reunited again - however, there's a twist! Is her brother really who he says he is? He certainly doesn't look like it in her photos...
The main female lead trembles a bit too much in every panel but considering her situation, we can't blame her because everyone seems like they're hiding a secret from her. She's in an unfamiliar environment and lives with practically strangers in the mansion. I'd be scared sh*tless too if I suspected ghosts.
The male lead is kind of giving off sociopath vibes? And why is he tormenting her? Oddly enough, I can't wait to see how this unravels.
Edit - dang, my curiosity got the best of me and I googled the novel spoilers. I had the hunch the sister was going through some mental episodes. The series kept hinting how her mother went crazy in the past, and then showed us scenes where her current "brother" kept mentioning his research and what Lilian thought about the relationship between genes, mental illness, and it being hereditary....

The story itself turns out to be very tragic (a little too much for my liking).
