How about that its change became a soccer game..
Shinichi-Ran v Heiji-Kazuha..
Even Ran can't play soccer, she just can kick that ball with her karate kid..
ShinRan would be owning..
Because Shinichi doesn't want Ran involve with BO.. In another words just to protect her..
She will be killed if she knew about Conan's secret.. I think Ran would accept that reason..
That's why Shinichi keeps the secret from Ran, isn't it??
