Aki, a swinger college student who is a Sub, feels an unidentified strong gaze during his play. It is Dom's "eyes of a beast" that make Subs kneel from their dominating glare. Since then, he has not been able to forget those eyes. Mitsuru, Aki's younger childhood friend who is a Normal, has always had feelings for Aki, even if he's aware that "Subs and Normals won't make a balanced relationship." Aki decides to do a part-time job for a clinical trial of a suppressant drug to pay for his college tuition and begins to look for a Dom who will live with him for two months. Mitsuru finds out and asks him to stay, but he's looking at Aki with the unforgettable "eyes of a beast"...!? "...I said it, didn't I? I'm going to make you obey me." Chapter counts include one extra chapter. (Source: Takeshobo, translated)
