Don't Worry, I Won't Bite: My Love Life With an Ex-Delinquent

After witnessing a tryst between her subordinate and an executive one late night at the office, Mihaya Hoshino suddenly finds herself betrayed by someone she trusted, and transferred to her company's branch in the boonies (also her hometown). Dejected and drunk after returning to her childhood home, she runs into Koda, the delinquent who confessed to her as a prank back in middle school. Years later, he now runs a farm that happens to be one of Mihaya's business partners. Acting as the new liaison, she must now work with the last guy on Earth she wants to see! It's an unexpected reunion between one clumsy-in-love former head class representative and a bad boy-turned-farmer!
