Shoto and Katsuki's marriage

Shoto and Katsuki are on their honeymoon after an arranged marriage for money so Katsuki can pay for his father's treatment after Masaru falls ill. However, Shoto keeps getting mysterious calls from his disapproving father. After overhearing it, Katsuki decides to go along. He'd never admit it, but he loves his dad. He'll do what Endeavor wants if it means keeping him alive and well. This will obviously be a todobaku fanfic, aswell as omegaverse.
