Chinatsu’s Graduation Speech
“Today, with the winter chill having passed and the buds on the trees beginning to swell, we third-years will be graduating from Eimei High School. I remember being giddy three years ago when I came to this new place, but I also shouldered regrets from junior high.
In order not to repeat those regrets, I headed to the gymnasium in the early morning every single day and practiced. I cannot thank enough my caregivers, as well as the teachers and staff at this school who made all this possible for me.
And above all else, I want to thank my friends. When I became a second-year and the ace on the team, I had a duty to lead them. But when I got injured, I thought that all my hard work had been for nothing. Even during times like that, my teammates gave me the energy to become stronger, and I had friends who stood by me and supported me. That’s when I realized that I’m not alone.
My regrets from junior high became things of the past. Instead of regrets, I took on responsibilities and finished what I set out to do in the best possible way. And today, we’re graduating.”

What to Expect From Blue Box Chapter 210
Blue Box Chapter 210 will likely conclude the Senpai Graduation Arc and return the focus to Taiki, Hina, Kyo, and Ayame as they move into their third year.
Hina is still not moving on from Taiki and has rejected Haruto for the time being indirectly. Kyo has a chance to move forward with Ayame after her breakup, but the story has not touched on it yet.
Taiki and Chinatsu have been dating for more than a year now, and their relationship will likely progress further as the school year changes. But as Hina is still trying with Taiki, a bit of drama is expected in the Blue Box as well.
