Honestly, Luo Jin could probably deal with the step-sister by himself if he really wanted to. It would be marvelous to see her put in her place by her crush 😈
I was going to light a candle for the step-sister, but then I realized that she is a terrible person and her misfortune should be celebrated at least a little! Thus... Snickering Snoopy Demonstrates Schadenfreude!!! Hehehe.
