Detective Haika

Also known as Midori Days. It's about Midori Kasugano who goes to an elite school and have a crush on Seiji from different school, without Seiji knowing her existence. Midori just looked at Seiji from afar and liked him. Then one day... Yeah... Midori become Seiji's right hand! Which is logically impossible. But well yeah, that's the author's fantasy. Got a problem? Knock on their doors. Despite that, it have great romance. I'm sure the author's focusing on the romance more than the plot. Especially in the anime. If in the manga, it's more comedy.

Thus, Midori have great days with Seiji. Seiji at first reluctant to play along, later he noticed Midori's true love and fell in love with her. Even though he needs to get along with some embarrassment about her bold confessions. Midori loves to make her shirts. And all of the shirts written Love Seiji. Since Midori is in Seiji's right hand, his real body is sleeping in a deep slumber which makes her mother really worried.

Midori have a childhoood friend named Kouta. He likes Midori. But that probably only revealed in the manga. I guess the anime doesn't really give hints to that. And Ayase who happens to be Seiji classmate, likes Seiji since he saves her from bad guys. If you really want to know the detail, you need to read the manga about Ayase and Kouta and others characters that are not in the anime. Because the anime is mainly romance in Seiji and Midori only I guess. I forgot to say Seiji is someone who loves to fight... Well actually he's only saving his kouhai, Miyahara everyday. I will say this bluntly, the manga's story plot is better than the anime. Besides it have a comedy, it also have better plot. 1st is Ayase confession, 2nd is Kouta feelings, 3rd is how Midori date is not in the anime (which made me felt so down she just disappeared like that). This story sounds like fairy tale doesn't it?

I finally realize something. That it can't stay this way forever. That I can't run away... Not from who I really am...
