2 is truly where Lilith really begin. Yeah the thing with the flashbacks coming between scenes when Jaehee and Sulhwa are making love can be annoying but it great showing Jaehee relationship with Huilin. The flashbacks are really cute at first, showing how good Jaehee and Huilin relationship could have been but it also show the problems it had, Jaehee wanting not to rely on Huilin for too much and work more to stand as her equal but Huilin doesn't see it like that. She only see Jaehee overworking herself and losing time with her while she know she have the money to help, soshe go behind Jaehee's back and she find out. Even when Jaehee broke out with Huilin, her own insecure keep her under her fingers and it's also effect her current relationship with Sulhwa. Side story was a nice reward from the drama of 2 as we watch healthy relationship with Young and Gyeowool. And the new art style when a great improvement, it really make the characters more pretty then the first series. I would recommend reading these 3 books but most chapters are just scenes of the characters doing BDSM, some of those scenes can get really uncomfortable for most people and can go to far at worst. Only reader if you can stomach it.
