I was possessed as an errand child who brought meals to the male protagonist who was captured as a test subject at the lab. If the experiment was successful and the male protagonist gained power, the lab would be engulfed in flames. So I tried to run away before that, but I felt bad for the male protagonist who was suffering from the cruel experiment. So I secretly took care of various things while avoiding the researchers' eyes. "Come to think of it, what's your name?" "I don't have a name......" "You make me one." "Huh?" I somehow became a little close to the male protagonist. "Are you going to abandon me? Don't do that." "Ah...... but-" "Anis, do you mind if I'm wrong?" "Ugh...... No. No, I don't." "Then stay by my side." However, the only one who can cure him who is suffering from the side effects of the experiment is the original female protagonist. I tried to help him and leave secretly so that he could find his partner...... "You promised not to abandon me. But, was it all a lie?” With the burning laboratory in the background, Emilien smiled with cold eyes. “A good child should keep his promises.” The temperature of the hand touching my cheek is cold. The red eyes close as if they are going to engulf me. “Answer, aren’t you going to tell me?” ......What should I do? I think I missed my timing to run away.
