SEKAI ICHI HATSUKOI - ONODERA RITSU NO BAAI THE CASE OF RITSU ONODERA 21 (REGULAR OR SPECIAL EDITION)
"I'm sure I'll never fall in love with anyone but you again."
Ritsu Onodera, an editor at Emerald magazine, has finally become "lovers" with Masamune Takano, her first love and now her boss at work. However, it's been over 10 years since they first met, and a year since they reunited. Instead of being overjoyed at this long-awaited happy ending, Ritsu is bewildered. Even though their feelings are mutual, it's only their first day as lovers. Not knowing what to do as a couple, Ritsu unconsciously avoids Takano, but it seems Takano feels the same way. The two become lovers step by step, experiencing ups and downs along the way. However, during a date Takano invites her on after work, they unexpectedly run into Ritsu's father...?
A slightly realistic love story in the publishing industry that will make editors turn pale.
