From what manga are the two from the credit page of chapter 16?

Probably a story about mc being a child of some villainous crazy guy judging on the style so find dad stories or family stories tags and you'll probably find it

Title?

I was just generalizing the genre I thought it was a part of, but you inspired me to find it and I did, if you search the rewards of marriage it'll pop up tho by a different title that's really long and I can't remember long enough to reply but it works if you search that title

I Found a Husband When I Picked Up the Male Lead i think

Thanks. (๑•ㅂ•)و✧
