Sister Pact, Love's Contract

Nora Collins is married to Colton Johnson on a contract, and her sister Vivian is married to his brother Graham on the same one. The two of them signed on as the Johnson family's paid daughters-in-law to save their orphanage. Nora trained in martial arts and does not back down, which is why she was put on Colton, the heir and the family's playboy. Vivian's assignment is Graham, who has shut himself away from everyone, and her job is to get him out of it. The arrangement was business: fix the brothers and get paid. The work is nearly finished and the sisters are getting ready to leave when Colton and Graham each realize they have fallen for their wives.
