To the Summer That Returned

My ex-boyfriend showed up as a new employee.

"It would be nice if you treated me as kindly as you used to."

For Lee Danbi, a professional in her seventh year, just getting through daily life is already a struggle. Now, her old flame, Han Yeoreum, is back to constantly shake up her world.

Why on earth did Han Yeoreum return? And can that passionate summer of the past ever come back to them?
