An Innocent Sin
Nayeon joins a secretive deviant club in order to see Jung Noah, a beautiful and mysterious watchman for the club. Noah has a twisted family life and has been sexually abused for a long time, but eventually his mutual love with Nayeon allows him to develop his first healthy sexual relationship. The plot is driven by multiple characters that have either worked for the Jung family or are actively trying to investigate the Jungs' murderous and abusive past, while Noah tries to disentangle himself from his family with the support of Nayeon and their other friends from the club. Great art and story, excellent smut value and charming MCs.
Dolphin Fairy
Suicidal loser Im Mokhwa falls for his handsome swim instructor, Changgyeong, and discovers that he is actually a bottlenose dolphin that turned human to look for his former trainer, Ji Hunyoung. Mokhwa almost leaves but Changgyeong learns to express his love and make Mokhwa stay. They become a happy couple. The second couple is Hunyoung and a transformed killer whale, Beom. This couple is better because they seem more realistic and complex as Hunyoung tries to "train" Beom who is highly intelligent, strong and aggressive. They fall in love and realize that Beom is wild at heart so they engage in a very touching long term relationship where Beom returns to the ocean for extended periods but always comes home eventually. First couple is a 3/5 mainly because Mokhwa is pathetic and irritating. Second couple is a 5/5, so the series averages a 4/5.
