Princess Minji had been haunted by "the faceless girl", waking up with scratches and cuts almost every morning. A young man shows, having connections to the incidents, but Minji isn't sure who to trust. With the timing of his arrival being suspicious, she is unsure which side he is on. She has learned that you need to always take people's word with a grain of salt. 

And now that she thinks about it, their love wasn't enough. It wasn't the love Siyeon needed. And even if what they shared was a beautiful thing, Siyeon wasn't ready.

Side effects may include - loss of hearing, tachycardia, jealousy, obsessive traits, increased libido, sunburn, and tiredness. That was what Siyeon wishes Bora had been labeled with when she decided to take her to the beach on their 2nd wedding anniversary.

Bora was going home from a long journey when she's attacked. It seemed like the end of the road as blood spilled onto the white snow as she lay cold and alone until something, or someone saves her. Will their relationship grow? Or will it crumble because of one's past?

When Bora wished for a family, finding one while under witness protection isn't what she had in mind.

A group of friends celebrate their Christmas eve as they do each year, together. This time, they reminisce together on how they all met. And some secrets are revealed.
