I'm going to say now that this series is not a story of pandering to fetishists who enjoy the prospect of dating younger girls. What Koi no Kotoba portrays is the the messed up relationship the two have after their life situations have pushed them into wanting to yearn for each other in order to lessen the burden of every day life. The relationship is never glorified, and both parties know full well the guilt that riddles them by being in the relationship. That being said though, it's not as if the two don't truly love one another and want what's best for the other.

Midori no Rupe has always been an author I've enjoyed seeing works from. His illustrations are cute and refined, yet his artwork has a distinct style of using extremely dark and heavy lines that perfectly portray the brooding, foreboding nature of his works. And his storytelling always has a good balance of dark and bright elements, to which this is no exception.

Overall, this series is one I would recommend to people looking for a short, emotional read. You might get something out of it.
