I seek this movie and can only provide the male actor’s lookalike picture

Here’s the male actor lookalike picture: (that’s George Eastman picture, but not the actor that I was looking for, he’s just the look alike)

Then if I find the actor, I could find the movie which is about a female doctor(iirc) who believes that love is all chemical interations in the brain, I think, if I remember correctly(aka iirc), and I remember that the guy says at some point that “cats are dicks” or “cats are assholes” (not really sure which, or if exactly that)

It’s a romance/romantic movie, at least. Probably made between [2016-2020] but I think it’s more like [2018-2020]

I’ve been looking for this for only 3 hours now…

Thank you in advance for any help.
