Blue Box, also called Ao No Hako, is one of the hottest sports-romance anime right now. It started airing in October 2024 during the Fall season, and the studio has confirmed it will run for two parts (two cours) back-to-back.
Right now, the second cour is ongoing, and Blue Box Episode 15 is set to drop this week on Netflix Japan. The anime is adapted from the manga of the same name and is available exclusively on Netflix.
After the latest episode, fans are super curious about Taiki and Chinatsu’s relationship. Do they end up together? And if they do, when does it happen? Especially since Hina recently confessed her feelings to Taiki, leaving things even more complicated.

Do Taiki and Chinatsu End Up Together in Blue Box?
Yes, Taiki and Chinatsu do end up together after Taiki confesses that he likes Chinatsu-senpai. But this won’t happen in Blue Box Season 1 since there are only 10 episodes left.

The confession takes place in the “Confession Arc” which comes later in the story. Starting with Episode 15, the “Cultural Festival Arc” will most likely begin.
Between the Confession Arc and the Cultural Festival Arc, there are two more arcs, and each will probably take 3-4 episodes to wrap up.

Which Chapter Does Taiki Confess To Chinatsu?
The confession happens in Blue Box Chapter 103, titled “I Need to Tell You Something.”
Taiki and his badminton team go on a field trip to Nagano. Before leaving, he had already made up his mind to tell Chinatsu-senpai how he feels after she gets back from her trip. Chinatsu was visiting her grandpa, just two hours away from where Taiki was heading.
When Taiki gets to Nagano, he thinks about sending Chinatsu a photo to let her know he’s there too. But then he decides not to because it might make him look desperate, especially since he already told her he’d talk to her after she returns.
Out of nowhere, though, Chinatsu sends Taiki a photo of Konami Lake, saying she went smelt fishing there because the lake was frozen.
After seeing the picture, something clicks inside Taiki. He suddenly tells his friends he is taking a detour and starts running.
Meanwhile, as Chinatsu is leaving the lake with her family, she gets a call from Taiki. She asks him where he is, and he tells her he’s near Konami Lake. Chinatsu steps out of the car, starts running toward the lake, and tells Taiki she’ll wait for him there.


They finally meet at the lake, and Taiki confesses that he likes her a lot. In Blue Box Chapter 104, Chinatsu confesses back, that she likes Taiki as well. They start dating afterward.
