I like the first and third story.... By the way, does the detective really got married?...

I don't think so since after Hotaru said "I came to see a happy married detective police" he added "but what are you doing?" So from this we can imply that instead of marrying a woman there he goes doing things on his own. Plus, for seven years he was looking for Hotaru so i don't think he can spare a time.

Thanks! I misinterpret it I guess
