Natsuyuki Rendezvous

Natsuyuki Rendezvous starts with a guy in his twenties, Hazuki-Kun, visiting a flower shop, and you hear him talking about his reason of visiting the flower shop regularly, and how his little greenery room is growing with the growing of his love towards the florist, Rokka-chan, who is almost 8 years older than him!!

Hyouka: You can't escape!

Kotenbu members

Kotenbu's four members find themselves interest in solving mysteries. Three of them depend on the one with the most logical, yet correct, solutions to the mysteries they encounter. This logical-member is Oreki, who thinks joining club activities, mingling with others, making new relationships  falling in love and anything that give's life its "Rosy-Colors" are energy consuming. He goes by his own made Energy-Conservation-philosophy "Don't do things you don't have to do, and rush the things you have to do". In other words, he is a lazy-introverted-bum! in a smart way. Sometimes... Oreki reminds me of someone I know very well... ehm...
Why would someone, who appreciate the "Gray life ", like Oreki would be interested in solving mysteries? isn't that an energy consuming task? well...
