Do you remeber what hata said about hayate's life partner..."try to figure out who has it but unsteady feelings of love"....If hata follows his line then this confirms that hayate will end up with someone...Also..hayate did say,"I don't intend to spend my entire life alone"(chapter 416)
Can you guess who might she be? ACCORDING to hata's sentence...not from your personal choice..
well ..to me I think it's nagi or hinagiku...Reason for nagi is that she is very inexperienced and also failed to express her feeling to hayate even after being his mistress..so she could be.....reason for hinagiku is that she is very shy when it comes to romance and also inexperienced....an unsteady feeling..
Athena is very experienced and strong when it comes to romance..Ayumu.....I don't think so..because hayate knows that she loves him...I don't think Ruka is the girl....neither maria nor chicharu...
So guys..please give your suggestuions
