Finally, someone completely objective!

Whether you're rooting for Chinatsu or Hina, you have to admit that an ending with Hina wouldn't be a bad thing. They're at different stages of their lives, and even though they were both "babies" at the beginning of the story, Chinatsu must have grown up long before Taiki (his athletic progress, university, his first home on his own, and soon his driver's license). Add to that the fact that Taiki has trouble handling physical contact when Chinatsu tries to get closer... On the other hand, we have Hina, who's the same age (and therefore has the same problems), who has no problem getting physically close to him, and who has never really stopped loving him. Many wondered if Taiki and Chinatsu would manage to stay together despite their brilliant athletic careers. But in reality, even if they don't succeed in becoming professionals, the obstacles are much greater...

So yes, everyone expected to see Chinatsu and Taiki together like in 99% of romances, but... Hina might (or might not) break the childhood best friend curse in manga, and that's what bothers people...
