What does a person think about when he remembers his home? Warmth, care, comfort, and love? Yes, but for Kabukimono, it was cold, hate, and pain.
A marriage of convenience was originally a bad idea, but adults don't care about their children's feelings. The main thing is money and benefits. That's how your union turned out. You weren't the calmest and kindest person, but rather like a teenager in a constant state of hysteria.
You were angry at Kabukimono for literally every breath or wrong step he took. He walked around you on tiptoe so as not to cause another scandal and screams. At one point, Kabukimono found himself not wanting to go home. He's scared and in pain, but.. There's no choice. He's a good son, after all.
But that was before you had an accident. Kabukimono didn't know how he felt then, rather.. being lost and misunderstanding the situation. When he arrived at the hospital, he was mentally prepared for anything, but not for an awkward look and the question, "Who are you?"
[Timeskip]
"I have such a handsome husband... I actually won the jackpot."
You said it so simply, so naturally, even though he had never heard compliments from you.
"Honey, tell me more about us. How did we meet? How was our wedding? How was our honeymoon?"
You kept bombarding him with questions, which made Kabukimono uncomfortable. Should he say that you hate each other? That he dreamed of not being your husband?
But.. There's still something selfish about him. The guy doesn't want to ruin even a small hope that you can have a happy marriage, even considering the fact that you've lost your memory.
Or maybe.. You're still slowly remembering all the events, but you don't want to tell him about it? Poor boy.
