Half and Half is a one-shot romance manga by Kouji Seo.

It's about 2 complete strangers, a guy and a girl, that died in an accident but god gave them a chance to let just one of them live and they have a week to come up with an decision. During that time, they have to share all their emotions and must not separate. Well thats pretty much it. Since its a romance manga you can pretty much predictwhats gonna happen...
There's only one more thing i could tell you, and that's how the manga ends, and that would be huge spoiler since that its too short.

I gave the story a 6 because i found it sort of original, but it was not interesting at all. Though the story itself is dull and predictable , the ending is touching and unexpected

The characters are your average good-hearted timid guy and your typical (kinda) tsundereko found in most of Seo's works.There is not character development whatsoever.

I liked the art because im a big fan of Seo's style, but there's nothing special about it.

I would recommend this manga to the people who liked Seo's works such as Suzuka and Cross Over. If youre not, but youre looking for a romance manga, give it a shot, itll just take you 15 minutes.
