Summary
"If you have an incredibly beautiful younger sister, anyone would
become a siscon."
Usami Aoi is a severe siscon, considering his mysterious-looking younger sister, Runa, to be the most beautiful in the world. When Aoi sprains his wrist, he starts receiving support from Runa and even begins to sleep together with her. Concealing her brother complex, Runa finds it increasingly difficult to suppress her feelings, gradually turning into a yandere. Updates with one or two chapters every day. The story primarily revolves around sweet developments between the protagonist and the heroine, without uncomfortable twists.

Ok, Two Important notices:
1.- Don’t get fooled by the “Completed” Status. It’s been on Hiatus by the author since 2021. This novel will most likely never be finished.
2.- For the Degenerates that want to know, they’re StepSiblings.
Now let me disclose the only two real characters in this story:
MC: Honest, straightforward and knows he’s “Odd” for liking his sis so much, BUT he always loses strength when receiving affection and commonly uses nosebleeds and anemia as a resource.
FMC: Sis, a real “albino” that goes from Tsundere to becoming a “brocon” throughout the story (I have not seen any Yandere behavior in the whole story) and becomes more and more sweet by accepting MC advances (and initiating herself in the last chapters).
There is also a Love Rival for the FMC, but she only appears twice in the whole story and motivates the FMC to become more proactive near the beginning. (MC has already told since Chapter 1 that he only loves his Sis, so no drama).
