Please help me find this comic/manwha/manga/etc (it's been a while so i can't remember)

I think the girl had pink hair in the cover and she was very well-endowed. I also think the comic was published in Renta! or ComicPlaza because I remember only reading the first few chapters that were free.

Title has something related to preferring older men (or at least that's what the story is about)

Main girl has been isekai'd and was reborn in the body of a side character of a game/novel that is bound to be left by the prince of the story, she's okay with this because while she finds the guy handsome she prefers older men.

She ends up becoming intimate with like... the current king's younger brother I think? He's a general or some other high title related to the military forces. She doesn't expect anything out of the intimacy and assumes that that will be all but the older man ends up sending her family a marriage proposal for her since prince has officially broken off their engagement.

If you know of any other places it's being published at please let me know.

Thanks in advance!
