I think he means how Uruka confessed, but decided to leave after all and let Nariyuki go. Uruka has a lot of fans, but the way the writing is going it seems that, like Nisekoi (just my opinion), each girl is gonna have a story arc where they come to terms and end things with the MC. Uruka was the most obvious since she decided to follow her dreams and not her love.
(The rest is also pure speculation on my part with no proof whatsoever, so take it with a grain of salt!)
Mafuyu is another favorite, but she expressed no romantic interest in the MC, but clearly has a lot of respect for him. She never expressed that properly so she may finally get her chance to follow her own dreams again with his help. Her story arc would be to clear things up with her sister once and for all and either return to figure skating (most likely as a coach) or renew her desire to help her students now that she saw how Nariyuki did it. Maybe both?
Asumi also never had a chance to me (which is a shame because she was my #2 favorite. I have a weakness for shortstack women). She is a major tease but also never really showed any true romantic interest. Her story arc would have to deal coming to terms with her dad and telling him the truth and finally succeeding the clinic.
Furuhashi has always been supportive of Ogata and Uruka, but has been in the closet about her feelings as well. Seeing as her issue with her father is mostly resolved and he accepted her path, I'm not sure what her story arc would be.
Ogata (my #1 fave because, yes, shortstack weakness. Hey, don't judge, we all have fetishes!) has always been struggling with figuring out emotions. She's gotten a lot better and made the most progress second to Uruka, personally. Then again, that's also why I suspect she won't win either: She discovers her emotions, but is too late to act on them. No idea what her story arc is either, but I know her dad would be involved somehow.
My prediction is Furuhashi will be the one getting the gold. And anyone who knows me knows that I am a horrible gambler so it's more than likely she WON'T win. Still I also wasn't expecting story after they graduated, so anything is possible...
Sorry, this is probably way more text than you wanted to read, but I was on a roll and couldn't stop
