At some point in the period covered in the first episode, between the Grand Prix Final and Yuri's return to Hasetsu, Yuri must have graduated from university.
At the Grand Prix Final, which is in December, Morooka speaks to Yuri and notes that he has not yet graduated.
Afterwards, when Yuri returns home in March of the next year, his mother apologises for not attending his graduation ceremony.1 Mari also notes that Yuri has a college degree, even if it took him an extra year.
Yuri also points out that he has not been back to Hasetsu in five years, and that he spent a period in Detroit:
I'm one of the dime-a-dozen top figure skaters certified by the JSF. I'm 23. My name makes me sound strong, but I finished last at my first Grand Prix Final. I still can't accept what happened! I even moved to a training facility in Detroit and worked hard to make the final.
Can we infer from this anything about where Yuri went to college? Perhaps he went to college in Detroit and graduated from a university there?
- Crunchyroll subtitles write the date as "March, One Year Later." However, based on what Yuri said about crashing through the rest of his skating season, it must only be a couple months after the GPF, rather than more than a year. The original text — 翌年3月 — appears to corroborate this.
