Tonight, my Sister and I
Step-siblings. Great love tension ! Both have another interested potential partner. So lots of jealousy. Lot's of hidden emotions. The author conveys the emotions perfectly. Very good.
Liar x Liar
Minato and Toru are steb-siblings who don't ever talk. One day, Toru meets Mina, the replica of his sister and falls deeply in love with her.
Onecha.
Touri is sexually obsessed by his sister Momoka. This is more like a porn type than an actual love story. Drawings are good. This is twisted and thus not for a young audience.
Uchi no Otouto-domo ga sumimasen
Step-siblings learning to live together. There's a competition between the eldest daughter and eldest son, that makes there relation hard to define. They don't see themselves. It makes it quite funny. All the characters are very sweet. This is, in the same time, cliché, and in the same time, extraordinarilly original. Light, fun and soon romantic. Vol 3 ch21 Hahahahah ! "Lips are just a part of the face, a part of the face is also part of the body, we are part of the earth, earth is part of the universe ! ...In the Ferris wheel :"Would you like to take one more turn" That was hilarious ! Waw ! I'm loving the new development ! Shuu is challenging his older brother ! Can't wait for more chapters !
