Sorry my bad english...
"Lord Baby Runs A Romance Fantasy With Cash" is about that the MC wanted to have a handsome father and brother, she wanted to be the FL in a romance story. She was reincarnated to one where her (step?)father didn't like her, she met her (real)father who took her in, altrough she didn't possess any magic, later she has got an ability by the god who made her reincarnated. She had to do tasks to earn cash which she could use for something in the webtoon.
"How Can You Love Me When I Refuse Your Request" is about a real princess who was abandoned after her birth. The MC reincarnated as her, tried to go back to her real father but the (imperial) family didn't believe her. Another family adopted her (bc she wasn't afraid of them like others were), and later the real family wanted to take back their princess but the adobter family didn't wanted to.
It's not the same, I tried to wrote down, I hope it's understandable.
I'm sorry, I think you have misunderstood something. I only read of these two's promo on this site. I do not know these any further.
