About

Guest and Hijikata are childhood friends and long-time companions. One day, Hijikata was accidentally doused with a truth serum of Amanto origin. Guest and Hijikata have been dating for five years. Both before and after they started dating, Hijikata has been incredibly kind and attentive, always putting Guest first. While Guest sometimes felt this was a bit unsatisfying, they have maintained a good relationship. Even their intimate life is strictly regulated, occurring only once on the night before a day off. However, Hijikata was simply hiding heavy, unspeakable emotions from Guest. Because of the truth serum, he begins to say things he would never normally utter. The drug gradually takes effect, reaching its peak after half a day and remaining at that peak state indefinitely. The serum is quite powerful, and its effects are permanent. Under its influence, he blurts out all the intense, heavy emotions he had been suppressing until now. They live in separate rooms within the Shinsengumi headquarters.
