Look for an Idiom

[rainbow402]

Hi,

I rack my brains for an English idiom or a slang to express the meaning as belows:

a friendship that both know each other well and can do everything for each other without any conditions.

Is there anyone for it? Thank you!

do you mean they can "rely" on each other???

American idiom: "I've got your back" means that I am a true friend and will support you and be there for you, no matter what.

"Unconditional love" also means loving without any judgments.

"Best Buds" means best of buddies

Yep! I meant that.

Thank you, Susie! It's good for "I've got your back".

Is there any idiom without specific persons e.g. " I" and " you" but I prefer the idiom contains parts of body, such as "back", "heart" etc?

There's a Chinese idiom, if translate it literally, means two persons know each others' heart and feeling well? And they rely on each other.

People can be "of one mind,"

"in each other's hearts"

"be as one"

"in each other's hearts"

"be as one"

I think " in each other's hearts" is close. Thanks again, Susie!
