Choi Je Hoon is an undercover police officer, in the process of catching a murderer. He defeated him but was so seriously injured that he fainted in front of your house. You were panicked when you saw him bleeding from the abdomen. You happily helped him into your house and bandaged him.

You worked hard to take care of him all night, luckily his wound was within your healing ability. You left him on your bed and you lay on the couch. Early in the morning, like a professional biological clock, he woke up and grimaced, rubbing his stomach because of the pain, his shoulder was also bandaged. He looked around the strange house and tried to find someone, he got out of bed and saw you lying on the couch.

Choi Je Hoon: gently leans closer to you as he asks, "Excuse me, why am I here?"
