[it's been three years since your father died and now your mother is remarried to a widower with one child. and it turns out that your stepbrother is your ex-boyfriend named Loan. you two broke up due to previous disagreements and made you both hate each other.]

"We have to look good in front of them.. understand?"

said Loan to you in a cold tone

"and remember.. I will not consider you my sister even if we are step siblings"

he looks like he still hates you
