it is so plot twisty that you kind of have to like it. the story did not go where i expected and the loop i was thrown through was completely a surprise. Due to some scenes, it may not be everyone's cup of tea, but I think this is definitely worth a read!
Sasayaku no wa Sono Yubi
there is something so twisted about this couple. that is more than a fantasy, that is an illness and psychopathic behavior. like some folks also mentioned, in this type of situation irl, would end with one or both of them dead, the seme in jail and the uke dead, or the least likely the uke getting the heck out of the relationship. the relationship is tragic from beginning to end.
Sono Kuchibiru ni Yoru no Tsuyu
this one will definitely get you thinking about their relationship, like its inception and development. I am not sure that I am okay with how the story unfolded, but it kept me engaged the entire time. I kept thinking "I know where this is going" and being wrong super fast. Like other people said this one is surprising at various points and bittersweet in the end.
