Description

What? My lazy, coquettish and evil elder sister is not related to me by blood? What? She wants to be a big star. Luckily, I have an omnipotent system, so I can help her clear all obstacles! What? Mom and dad asked me to help her with her singleness. I'm still single! Why don't you care about me? System: I think you're a good match. I'll set you up. No, I refuse. I'm miserable to be her younger brother! I don't want to be my own brother-in-law!
