It's a Chinese novel. Chinese name is 我和妹子那些事. The NU link is this page: https://www.novelupdates.com/series/regarding-those-matters-of-me-and-my-little-sister/ There's only one English chapter up there so I am asking those of you who can read Chinese if you have read this novel yet. And the reason I am asking is because there's too little information even on those Chinese sites. All I can see so far are the city, romance and mature tags. But in Chapter 1, the protagonist's sister got raped. So I am just curious if this is going to be an action-packed revenge novel? I am reading the second chapter now but it's kinda depressing so unless there's going to be revenge and weak-to-strong stuff later on, I really don't want to continue reading this. If any of you has any information about this novel, let me know.
