Repost of the Summary and some Explaining

I've never known Haruto Takase very well. He has always just been 'the guy who takes the next shift at the convenience store' to me. A fairly plain looking boy, who, although being extremely clumsy, really didn't stand out much. If only I knew that after a certain accident, a visit to the hospital, and an eccentric inventor, I would be closer to Takase than ever before....

.....well, his cells at least.

(If ya can't tell this is cells at work)
