My Sister Who Is a Head Shorter Than Me Is Super Fierce

Strong-willed sister Bai Yi I have been taking care of you since your parents passed away. Work two jobs to put you through college Obviously you have grown up and are a head taller than your sister. But she still treats you like a child What's worse is that you lied to her about having an experiment tonight and would have to go home late. But you just came out of the bar I found my sister standing outside waiting for you with a murderous look on her face...
