Blue Box Season 1 is now finished, and with Season 2 already confirmed, a lot of people are waiting to see how things move forward between Taiki and Chinatsu. Now that the love triangle is done and Taiki has rejected Hina, he is more sure than ever about his feelings for Chinatsu. But if you are expecting a quick confession, it is not happening just yet.

The first season adapted everything up to Chapter 79, ending right after the Autumn Training Camp Arc. There was also a short flashback from Chapter 80. The anime closed right before Taiki and Chinatsu’s shopping date, which a lot of fans, including me, have been looking forward to for a while. So if you want to continue the Blue Box story from where the anime left off, start reading from Chapter 80.
After Blue Box Chapter 80, the manga starts a new arc, Yumeka’s Return Arc, and not long after, the manga heads into one of the most awaited arcs, the Confession Arc. The manga is still ongoing and is currently at chapter 193.
Blue Box Season 1 covered a total of 9 arcs, and now only 3 arcs are left before the First Year Saga ends. Once that’s done, Taiki, Hina, Kyo, and Ayame will be promoted to the second year, and Chinatsu will become a third-year.
