What is the plot?

Rei is stranded on a stormy road at night when Arashi finds him and helps him, and that rescue becomes the starting point of their relationship.

After Arashi's assistance, Rei's gratitude deepens into stronger feelings, and the two grow closer as the episode's central relationship develops around that first encounter and its emotional aftermath.

In a parallel thread, Rei's friend Kai becomes involved with Fuma after a bad encounter, and the episode presents that connection as a second major relationship line that advances at the same time as Rei and Arashi's.

Kai then accidentally discovers the relationship between Rei and Arashi, which creates a significant turning point in the episode because it exposes the hidden connection to someone outside the couple.

Even after that discovery, Fuma continues showing Kai affection, but Kai remains unable to let go of the painful memories that still affect him, so the episode closes on unresolved emotional tension rather than immediate resolution.

What is the ending?

Kai discovers that Rei and Arashi are together, and the episode ends with that realization hanging over him. Fuma is still openly affectionate toward Kai, but Kai cannot move past what he has just seen.

Scene by scene, the ending plays out like this:

Kai is the one who first reaches the point of surprise and tension, because he accidentally uncovers the relationship between Rei and Arashi. The episode's final movement focuses on that discovery rather than on a large public confrontation, so the emotional center is Kai's reaction.

At the same time, Fuma continues to show Kai clear affection, but Kai's attention does not fully return to him. The story leaves Kai in a conflicted state: he has Fuma's attention in front of him, yet his mind stays fixed on what he learned about Rei and Arashi.

Rei and Arashi's relationship is revealed to Kai, and that revelation is the ending's key turn. The episode does not present a separate, resolved fate for them in the available synopsis; instead, it ends with their connection exposed and with the consequences still unfolding around the other characters.

So, by the end of the episode, Kai is left unsettled and emotionally occupied by the truth he uncovered, Fuma remains actively affectionate toward him, and Rei and Arashi remain the couple at the center of the newly revealed relationship.

Is there a post-credit scene?

I can't verify a post-credit scene for Episode 5 from the available results alone. The episode listing confirms the episode exists, but it does not describe any end-credit or post-credit content.

The other results are not reliable enough to confirm this specific detail: one is a YouTube title page that does not provide episode-by-episode scene breakdowns, one is a playlist index without episode content details, and the IMDb result is for a different entry, "Special 1," not Episode 5.

If you want, I can help you assess likely post-credit content by comparing Episode 5 recaps, reactions, or the stream itself, but from these results I cannot state that there is definitely a post-credit scene or describe it accurately.

How does Kai discover the relationship between Rei and Arashi in episode 5, and what does he do after realizing it?

Episode 5 centers on Kai accidentally uncovering the relationship between Rei and Arashi, which is the key plot turn identified in the episode synopsis. The available synopsis does not spell out every step of the discovery, but it makes clear that Kai learns the truth by accident rather than through a planned confrontation.

What is the significance of Fuma’s continued affection toward Kai in episode 5 after Kai learns about Rei and Arashi?

The episode synopsis specifically notes that even after Kai discovers Rei and Arashi's relationship, Fuma keeps showing him affection. This makes Fuma's attention to Kai an important character beat in the episode, because it continues the romantic tension around Kai at the same time his focus is pulled toward Rei's secret.

What happens between Rei and Arashi in the stormy-night scene that leads to their relationship deepening?

The story setup for the series says that on a stormy night, Rei is stranded on the road and Arashi helps him, and that Rei's gratitude develops into a deeper relationship with Arashi. Episode 5 is the point where that relationship becomes exposed to others, so the storm encounter is the key earlier plot element tied to this episode's developments.

How does Kai’s friendship with Rei affect the way he reacts to seeing Rei with Arashi in episode 5?

Kai is described as Rei's close friend in the series premise, which makes his accidental discovery of Rei and Arashi's relationship especially personal. Because the episode synopsis only states that Kai uncovers the relationship, the strongest supported inference is that the reveal matters to him not just as information, but as a breach in the trust structure of their friendship.

What role does Fuma play in Kai’s storyline in episode 5, and how does his dynamic with Kai develop?

Fuma's role in episode 5 is tied directly to Kai, because the synopsis says Fuma keeps showing Kai affection even after Kai learns about Rei and Arashi. The broader series premise presents Fuma as one of the two "saviors" who stir romantic feelings in the central pairings, so his interactions with Kai are part of the episode's romantic push rather than a separate subplot.

Is this family friendly?

No, this is not especially family-friendly. It is a BL romance series, and episode 5 is described as involving relationship tension and a "horrible encounter," which suggests emotionally intense content rather than a child-oriented tone.

Potentially objectionable or upsetting elements for children or sensitive viewers may include: - Romantic/sexual relationship themes between male characters. - Emotional conflict, jealousy, or relationship discovery in episode 5. - A "horrible encounter," which may imply distressing or upsetting backstory material. - Storm-related peril and stranded-in-bad-weather tension in the series premise.

I can't verify the exact scene-by-scene content of episode 5 from the available sources, so if you want a stricter suitability judgment, I'd treat it as best for older teens and up rather than younger children.
