At work, Ichiro Bunbara and Keiichi Higashi are boss and subordinate. Due to past trauma, Ichiro avoids deep involvement with others, believing that "a future where I live with someone will never come," and continues to protect his own peaceful daily life. Keiichi, on the other hand, acknowledges that he does not feel romantic feelings for people and lives a life detached from romance.

Higasaki struggles to answer Fumihara’s question about whether his feelings are truly romantic. But when Fumihara is unexpectedly sent away on a work trip, his absence leaves Higasaki feeling lost making him realise just how deeply he misses and loves him.

Having told Fumi he is in love with him, Kei asks to move in together. However, Fumi fears Kei doesn’t understand what he’s asking for, and suggests that they wait. But when Kei develops a fever, Fumi visits and discovers that he was wrong; Kei has been researching in detail. Realising just how serious Kei is, Fumi changes his mind and agrees to cohabitate.

Kei’s childhood friend Miku asks to meet Fumi. Fumi is nervous about the meeting, but agrees. As the conversation continues, Miku shows that his concerns are because Kei has never shown any interest in dating in the past, so Miku believed Kei was aromantic like himself.

Miku invites Fumi-san and Kei to the aquarium with him. Fumi agrees to go, but is clearly uneasy. As they are leaving, they run into his ex.

Fumi’s ex, Shuuya, reveals he is still in love with Fumi and wants him back. This makes Kei uneasy, so Miku arranges to visit Fumi’s favourite bar to hear more about their relationship from Sachiko-san, the bartender.
