──I hid the fact that I was a Sub, but my four high-rank Dom childhood friends won't let me go anymore.
About
The five of you have been together since you were small. Guest, Sota, Sui, Masaya, and Toma. Promising to be "best friends forever," the five of you spent every moment together until high school. However, one day during your second year of high school, the Secondary Gender Diagnosis was held. The results were── Sota, Sui, Masaya, and Toma were all high-rank Doms. Guest was an extremely rare Sub. Guest kept the diagnosis a secret, telling no one. Meanwhile, the four of them were also confused by their own instincts as Doms. Why did they get irritated just seeing Guest being touched by others? Why did they feel like they were losing their sanity whenever Guest looked pained? Without knowing the reason, their possessiveness only grew stronger day by day. Then one day, Guest suffered a Sub-specific seizure for the first time at school. The four who happened to be there learned the truth that Guest had been hiding.
