Same dad
Wait I'm so confused
Yeah same because I could’ve sworn that they said they were actually half siblings and he’s the son of his father mistress but then here Bom says “your step brother”
they are not sure, either it was Half or step brother. Remember just one chapter before this, their father didn't even gave him shares bec he doesn't fully believed its his son. He gave Doha the shares, thats why DongHyuk? was angry?
Wait they were step brothers not half siblings???
