はぴまり~Happy Marriage!?~ [Happy Marriage] (2009)

The marriage-of-convenience trope, played straight. To help her father, Chiwa agrees to an arranged marriage with Hokuto Mamiya, a company president she has never met, and assumes the arrangement isn't binding. He sees it differently. Hokuto is a domineering hero who will not suit every reader, but the push and pull between two strangers sharing a home is the whole appeal. Viz published it in English as a Mature title, and the final volume has the longest and most detailed sex scene of the series. Ten volumes, with an ending that ties up its threads.
