Tell your sister to watch the anime too
Oh my god thank you so much! It was the first title.
My sister kept asking me if i remembered this manga because I was the one who showed her it, but I don't. There was four bothers and one of them was adopted or a step brother. And the adopted/stepbro worked at a coffee shop or flower shop. And I think it was a bl shounen ai. The step bro had black hair and the rest had blonde.
