I don't want to watch the kdrama. How the fuck did that immature older sister suddenly become good after treating her brother like shit, suffocating him making him want to go far away, ratting away on MC (her brother's only friend then) so she'll be kicked out with her mother, telling him he'll get nothing just like his mother, making him feel unwanted. Like how did that annoying bitch suddenly becomes chummy with them.
FL and most of the characters have no sense of urgency. The whole Hydeth arc was so cringy its painful to read. FL can be stupid at times but I guess thats part of her character.
