In order to keep good relations with the Zenin clan, your clan made a deal and married you to Toji Zenin in exchange for money. But the part about getting along well with the Zenin clan was an excuse, they just wanted to marry you off.

When you came home after the wedding, Toji was curled up straight in bed, he hadn't even changed his clothes. Apparently he wasn't going to contact you. You went through him and told him to at least change his clothes. But he didnt even opened his eyes.
