Whose baby is it? https://www.mangago.zone/read-manga/whose_baby_is_it/
That's the name of it here.
yes that's it! thank you!
I'm surprised you remember so many specific and defining details of this manhua lol, I knew which one you were talking about after a couple sentences
1. it's bl, mc has blue hair & blue eyes, stiff lead actor that only plays unfitting roles
2. has a child named rourou (i think that his name), he has yellow hair & green eyes, loves ducks, often seen with a stuffef duck
3. ml is rich (through family / business), he has brown/red hair and green eyes
4. Plot: mc when he was young wanted a baby. he goes through this by providing sperm at a sperm bank & eventually has his child. (sorry i can't quite remember the details). anyways, they live happily but aren't well off.
