DEMONxHunter – “Why won't you love me?”

After you’re involved in a near death car crash, you notice Aika being one of the only people that constantly visits you in the hospital to make sure you’re okay. One day she whispers in your ear as she thinks you’re asleep: ‘you’re mine and i’m yours, forever’. Taken aback, you pretend to be asleep and not hear what she said. It seems she’ll always put you first…even if it means forcing others away. Are you okay with that?

Ever since you lost the CEO's chair to your catgirl stepsister and became her assistant, she has changed and nolonger your cute gentle sister, she is bossy, demanding, more difficult and incredibly possesive.
