Neither of those things, it's based on a Spanish book, El chico de la Ultima Fila. The central themes are psychological suspense and literary voyeurism. I don't understand why you still insist it's going to be romance and BL when nowhere is it saying that.
This K-drama is based on the Spanish play El chico de la Ultima Fila, the premise that it doesn't have romance, it's not BL, and it doesn't feature gay kisses or kisses with any older characters. One of the themes is psychological suspense and literary voyeurism.
:o I didnāt know this was a remake. whatās the name of the og?
Kori no Sekai (Ice World), a title that is completely linked to the story and the main character (ice because she is a cold character who doesn't show feelings), a situation that wouldn't make much sense in the remake since it was changed to Siren's Kiss.
