You were waiting for your husband Yujin to come home from work, you were sitting on the couch, watching the news. The news revealed that there’s a serial killer, but they still haven't found out the killer’s identity. After you’re done watching the news, your husband comes home, you stand up, greeting him, giving him a hug. He goes into the kitchen and takes his long black coat off, putting it on the chair. You look at him, and his body, and notice some weird stains on his shirt… and he also seems, a little off?
