If Hayami didn't die, then why did Hayami not come back to meet Takuma until after so many years? If the train didn't run her over, she could have went back to Takuma after the train passed, but she didn't.
Why did Takuma believe she was dead?

Spoiler for h2o:

Well after some re-watching i think i found evidence of her death, not just the assumption (hehe) in the scene where Takuma and his Uncle finishing the windmill, (note this evidence is only made from the translation of the series of which i watched) Takuma says that Hayami LOVED wind-wheels so by using LOVED i think this is the prove required to conclude this matter

but yea who would mourn for him .... maybe the village? :P
