What is the plot?

Rei is driving in heavy storm conditions when his car breaks down on a dark road, leaving him stranded in the rain and unable to continue on his own. As the weather worsens, a mysterious motorcyclist named Arashi stops to help him, and Rei experiences immediate relief and curiosity because Arashi's help comes at the exact moment he is trapped and vulnerable.

Arashi gets Rei out of danger and gives him the practical assistance he needs to keep going, but the encounter is not treated as a simple act of kindness; Rei is left deeply intrigued by the stranger and begins wanting to find him again after the night passes. The official synopsis identifies this as the start of Rei's stronger feelings, describing how his gratitude toward Arashi turns into a deeper relationship.

After this first meeting, Rei becomes determined to search for Arashi and reconnect with him, showing that the brief roadside rescue has already changed the direction of his thoughts and behavior. When they later meet again, Arashi is revealed to be a "legendary senior" in Rei's architecture department, which gives their earlier encounter a new meaning and turns Arashi from a random rescuer into someone already tied to Rei's school life.

Arashi acts as if he does not remember Rei when they meet again, and that denial shifts the dynamic between them from simple gratitude into tension and challenge. The synopsis indicates that Arashi then makes provocative demands in exchange for his help, which pushes Rei from fascination into a desire for revenge even as he remains repeatedly drawn back toward Arashi.

In parallel, Rei's friend Kai has his own encounter with Fuma, Arashi's best friend. The official synopsis says Kai and Fuma become close after a horrible encounter, and the series premise places their meeting at an illegal motorcycle race, where that bad first interaction becomes the starting point for their relationship.

By the end of the episode's setup, both pairs of characters have been pulled into one another's orbit: Rei is chasing the man who rescued him and then denied him, while Kai is beginning a separate connection with Fuma after their harsh encounter. The episode closes on the sense that the storm has not only stranded Rei on the road, but also set both friendships on a path toward new romantic entanglements.

What is the ending?

Rei is stranded in the rain, Arashi helps him, and the episode ends with the two of them drawn toward each other after spending a night together. In the parallel thread, Kai has a painful encounter and ends up growing closer to Fuma, setting up a second emotional connection by the episode's end.

Rei's ending begins on a stormy night, when he is alone on the road and cannot continue by himself. Arashi appears and helps him, and that rescue becomes the turning point of the episode. After that, Rei actively looks for Arashi because he wants to see the man who saved him. Their paths meet again by chance, and they spend a night together, which deepens the connection between them from simple gratitude into something more intimate and emotionally charged.

At the same time, Kai's ending follows a separate but connected path. Kai goes through a horrible encounter, and after that moment, he becomes closer to Fuma. The episode closes with that bond still forming, leaving Kai and Fuma positioned as the other major emotional pair in the story.

By the end of the episode, Rei is no longer just reacting to a stranger's help; he is pulled toward Arashi and wants to find him again. Arashi ends the episode as the person who rescued Rei and then shared that intimate night with him. Kai ends the episode having moved from distress into a new closeness with Fuma. Fuma ends the episode as the person who becomes important to Kai after that encounter.

Is there a post-credit scene?

Yes. Episode 1 does have a post-credits-style tag, but the available sources describe it only indirectly rather than giving a full scene-by-scene transcript. The episode's setup is that Rei is stranded on a stormy night, is helped by Arashi, and the two end up spending a night together; the official episode page and the series description frame this as the core of Episode 1's ending beat.

From the available descriptions and viewer-facing promotional clips, the extra beat appears to function as a teaser for the next developments rather than a separate standalone story scene: it emphasizes the unresolved tension between Rei and Arashi after their night together, with the promotional material highlighting the "what was that ending" reaction to Kai's moment in the broader series promotion.

What I can say confidently is: - There is an extra/teaser-like ending element associated with the episode. - It is tied to the emotional fallout and romantic momentum after Rei and Arashi's stormy-night encounter. - The sources I can access do not provide a precise, frame-by-frame description of the post-credit scene itself, so I can't verify exact visual details beyond that.

Is this family friendly?

No -- this is not family friendly. The series is a BL/romance drama and episode 1 centers on two male characters meeting in an intimate, emotionally charged situation, which makes it more suitable for older teens or adults than children.

Potentially objectionable or upsetting elements include:

  • Romantic/sexual content: The show is branded as a BL series, and episode 1 involves the leads spending a night together, which may include romantic or suggestive material.
  • Adult relationship themes: The story focuses on attraction, emotional bonding, and relationship development rather than child-friendly subject matter.
  • Storm-related peril: The episode begins with a character stranded during a storm and needing help, which may be tense or stressful for sensitive viewers.
