Perhaps 'I Can't Believe My Little Sister is This Cute' is the inspiration? As an elder brother myself I would never allow for such behavior from my siblings without 'proper' correction. He's a wimp.
Shameless Promotion:
Do you want to read a Comedy-Fantasy Novel that has Satisfying Story, built with Memorable Characters, who are Multi-dimensional, Realistic, Interesting, Flawed, Competent, Sympathetic, and Likeable? Do you also want to see a group of Characters who'll develop along with the Shocking Plot, binded with Complicated Conflicts, which takes place in an Epic World made from the Combination of Eastern and Western Fantasy? Yes? Then, you better check out my Fookin Novel: Crowning Cruel Crow. May God Bless You with Good Health, if you ever leave a review as well as comments. Hahaha.

The author said there would be no ****** there, does it mean that MC wouldn't romance his step-sister, or that the author is actually smart enough to not consider it as ****** because there is no blood relation? If it is the former, then the title of the novel is really misleading and should be changed, lol. If you don't want them together then why making them no-blood-related?
uughhh*yawns*...I can relate this very well. the typical rude step sister or a tsundere I suppose? very much annoying but will still continue my reading ahhaha
