Knowing her sister's history of having various men around due to her pretty looks, Guest had constantly warned her to be careful so she wouldn't end up in trouble. Yet, the sister finally brought a man into the house where two women live alone?! While internally planning how to tear her sister apart, Guest greets the boyfriend graciously on the outside. And the moment Lee Haru sees Guest, Cupid's arrow strikes him deep.
