Help, My Sister Won't Leave Me Alone!

If Su Jin has no ability, she can broadcast it. To be honest, there is no need to waste too much ink on an ordinary person. It is good to dig holes in the early stage and then slowly fill them in, but don't dig too many holes. Tomatoes are now fast-food novels. Digging too many holes will easily lead to failure. Don't be a eunuch. I have read many better yandere books and they all have less than 100 chapters. Also, I am a loser and I love to read 🥰 🥰 🥰 🥰

It's okay to wrap it up, it feels like it will have a big framework, I hope it won't be unfinished

What's the background? I don't understand. Is my sister the only one with this ability?
