Oh my god, we're in the loop.
Ju-Won's father relationship with Hae-Jun is sufficient enough to be called Family by Choice.
Familial bond in the drama is your expectation.
"it should've related to the content" its a rule set by you.
There are a lot of other show, that its title didnt related with its content.
"Chariots of Fire", didnt have chariot or fire in it.
"The Seagull", no there is no seagull in it.
"Go Ahead", why they chose this title if 1/3 of the story is about family?
Actually I think the expectation is because it is an adaptation after all and the focus of the original drama is family.
If the drama was an original they could've named it whatever they wanted and they'd be no problem what so ever.
But in the end, I understand your pov, for you is enough the tittle is only refers to some characters. For me I kinda feel the title is misleading because I don't get the familial bond in this version at all and I feel the main focus and the drive for all the creative choices they made is to enhance the romance.
