After Pretending to Live Together, the Senior Refused to Leave

In order to deceive her control-freak grandfather, the poisonous-tongued young lady is forced to pretend to live together with her lazy senior.

But when he said, "Don't believe me, I may betray you at any time," she realized that she seemed to have picked up the most troublesome fake boyfriend.
