The Tyrant Falls in Love

Plot

The story picks up on Morinaga and Souichi's story where Challengers left off. Tetsuhiro Morinaga is a university student with a four-year-old crush on his senpai, Souichi Tatsumi, whom he assists with his research projects. In Challengers, while sick with a cold, Morinaga inadvertently confesses that he is gay and in love with Souichi. Following this, he believes that Souichi now hates him since he is homophobic and says he will leave school, but Souichi cares for him and insists that they forget about it and remain good friends. Their story ends with Morinaga convinced that his feelings would never be reciprocated.

The Tyrant Falls in Love

At the start of The Tyrant Falls in Love, in 2004, a year following the events of Challengers, Tomoe and Kurokawa recently moved to California for Tomoe's new job when Souichi hears that California has just legalized gay marriage. Souichi furiously calls Tomoe to tell him that he should not get any ideas about getting married, but Tomoe has not heard the news since he has been busy working. In effect, Souichi's call does the exact opposite of what he wants, and Kurokawa and Tomoe run off to get married. Meanwhile, Morinaga laments to a friend about his unrequited love for Souichi, who in turn gives Morinaga a special drink that will make Souichi more compliant. Morinaga tries to throw it in the trash on his way home but is uncomfortable with the thought of someone else finding it and reluctantly takes it home and hides it in his cupboard. The next day, Souichi runs around yelling that he's going to go to America and kill Kurokawa and get a green card so he can become the Governor of California to re-ban gay marriage. Morinaga convinces him to calm down and drink with him instead, so he goes to Morinaga's apartment to drown his sorrows.

The Tyrant Falls in Love

After Souichi drinks all the alcohol they have bought, he demands that Morinaga go out to buy more. While Morinaga is out, Souichi searches his apartment for any alcohol he may have, finds the hidden drug-filled wine bottle, and drinks it, not knowing it is drugged. At first, it appears that it has no effect, and Morinaga believes his friend tricked him. They go to sleep, but Souichi wakes up at night to find himself aroused and unable to move his body properly. He tries to sneak off to relieve himself, but due to the effects of the drug, his weakened body trips and wakes up Morinaga. Morinaga sees that Souichi is aroused and understands that the drug Souichi has taken works. Thinking that Souichi would never return his feelings, Morinaga takes advantage of the situation. Despite Souichi's weak refusals, telling Morinaga to stop, he goes on to rape him.
