It has the same Author, Producer, and Writer of Junjou Romantica. It is connected to Junjou Romantica because of the same venue of Marukawa Shoten
The anime is kinda cliche, if you read the manga.
Some of the characters already appeared in Junjou Romantica.
REVIEW:
Broken-hearted by his First love at 15, Onodera Ritsu (now 25), leaves his father's company due to his co-worker's jealousy and now works at Marukawa Shoten and is now ready to become independent. Ritsu meets his new boss, Takano Masamune, later on he discovers that Takano turns out to be Saga Masamune (his high school first love).
It's not your typical "First love never dies" theme series, you can actually learn lots of lesson from this slice-of-life anime.
The art style is the same as Junjou Romantica. Ritsu is a combination of Shinobu and Misaki. Frankly speaking, This anime is hotter than Junjou Romantica.
I Love the humor of this series and also the plot of the story, it's easy to understand.
