Kōtarō Yuda, nicknamed “Judas,” became the center of a classroom legend alleging his involvement in a murder. Childhood friends with Hana Arai, he distanced himself as teens, rebuffing her romantic overtures. On Valentine’s Day, Hana gifted him a handmade marriage certificate, which he callously dismissed before distributing replicated versions to female classmates, sparking jealousy and emotional chaos.

Hana retaliated by slipping a bee into his collar, unaware of his lethal allergy. Coinciding with his abrupt transfer announcement, the sting triggered a severe reaction, fueling rumors he had died from anaphylaxis. This incident solidified his enigmatic reputation and drove Hana to withdraw from school, consumed by guilt.

Post-transfer, Kōtarō remained aloof, indifferent to Hana’s remorse. Years later, during a meeting arranged by Alice Arisugawa, he confronted her, coldly vowing never to forget the pain but refusing closure. His detached demeanor persisted, though the acknowledgment hinted at unresolved echoes of their past.

Rumors and his actions forged his legacy as a tragic, mysterious figure, marked by emotional isolation and the fallout of impulsive choices. The ambiguity of his true sentiments and fractured relationships left his story steeped in unresolved tension, a testament to youth’s recklessness and its enduring scars.
