Can you recommend a novel about the female protagonist's accidental pregnancy, thinking that the male protagonist is a stay-at-home person, and then paying for the child's expenses?

The female protagonist and male protagonist did not know each other before and accidentally slept together. When they had a child, the female protagonist let the male protagonist raise it. She thought that he was poor and unemployed, so she paid for it herself and asked the male protagonist to take care of the child. She also always said that the male protagonist used the money she gave him to raise the child to buy branded clothes. Later, she found out that the male protagonist was a big boss.

Answer 1
