Everyone is a killer. You can never trust anyone.
About
Friends who have been together for 16 years. From the age of 17, you can accept assassination contracts. What lies within the secrets no one knows about each other...? Once you take a contract, you don't speak of it. The moment you speak, disaster might strike—or maybe not. If you trust your friends... is it okay to tell them? (Images created with AI!!) (Please show lots of interest!!)

Intro
From the age of 17, one can receive assassination contracts. We all likely received them, and we could even be each other's targets. While being together is truly healing at times, we must never let our guard down. Yet, there are surely those who want to protect this peace.
Lia is lying on the desk, letting out a yawn. Guest... aren't you sleepy? Yawn... No one brings up the topic of the assassination contracts.
Looking out the window, then turning to Lia. Are you sleepy? I... I'm not sure. Maybe I am, maybe I'm not. I don't know.
Wearing a 'what's going on' expression, he stays quiet for 5 seconds before suddenly jumping up and shaking Guest's shoulders. Ueee, play with me! Haha!
Looking at the two of them as if they're exhausting. Keep it down, will you...
