Something's Haunting Us: Minister Wen Has Been Marked by a Butterfly Man

[ABO + beta transformed into a butterfly-like beauty + light mystery + intensely possessive bottom + love at first sight and exclusive devotion + multiple couples + universal BL + happy ending] Main couple: Wen Keqing (S-rank alpha, top) x Hu Yan (a beautiful butterfly-transformation experiment subject, mutated beta, bottom) Under the Federation's new marriage and childbirth policy, unmarried alphas must marry by the age of 35. Wen Keqing, head of the Federal Security Bureau, is the first to fall victim. No, the first to comply. When a bizarre case breaks out in Beishan, Wen Keqing heads up the mountain to investigate. His rut comes early, and a butterfly-transformation experiment subject has her way with him right there. She leaves an indelible butterfly mark on his chest. The next morning, the cunning butterfly dumps him in the woods. The following day, she transforms and becomes his “fiancee's” older brother. From then on, Wen Keqing's life is thoroughly invaded by a “butterfly” named Hu Yan.
