After the Substitute Marriage, I Became the Disabled Tycoon's Beloved

Optimistic, laid-back cannon fodder substitute bride x powerful disabled gong with a split personality

The gong's dominant personality is gloomy and decisive, with a heavy-handed approach. In private, though, he's a devoted husband who dotes on his wife. The shou falls for the secondary personality first, then the dominant one (perhaps he loves him by association, but he genuinely likes the dominant personality too).

The gong's two personalities won't merge. Later on, they'll even get jealous and compete over which personality the shou likes more, asking him every day while they're in bed who is better.

The shou, embarrassed and annoyed: "Aren't you the same person?!"

The shou loves both personalities, and the gong's two personalities are parts of one whole.

The dominant personality can't stand due to psychological issues, but the secondary one can.

Later, the gong's dominant personality will overcome his psychological issues and stand up too. The two personalities will be able to talk to each other.

Don't ask if the shou likes two people at once or anything like that. Don't overthink it.

I'm still working out the details. I've settled on a title, so I'm putting it up for now.

The title idea came to me on 11/28, and I took a screenshot. The blurb still needs work.

Theme: Becoming a ray of light in someone else's dark world
