Both of their parents are not getting married, they broke off the engagement because they chose their son's happiness and accepted their kid's relationship.
And technically yes, if both the parents (remained in their engagement and eventually married) the woman's kids last name would've change to dongwoo's last name.
And their brother don't end up together because dongwoo's younger brother is straight. (Though I understand the sentiment, they would've made quite the couple too.)
No no they won't have the same last name. The twins is under the custody of their biological father. So technically they dont need to change their last name. Usually when parents divorce kid will use the last name of the parent who got the custody.
Yes I know that, but didn't the mom had custody of all 3 of them?, she just chose to take the older brother with her and left the twins with the dad because the older brother was more of their favorite and to spite her ex-husband she only took him, making the twins believe their mom didn't care/love them?. Or am I remembering that wrong?. I thought that was mentioned in one of the chapters. I'll go back and re-read it again just to be sure.
Like i mean ibguess it's ok even though their parents are getting married. They are not blood relate or anything. There is also no changes in their last name watsoever soooooo... I dont see a problem if their parent get married while they are in a relationship...
ALSO!!! I lowkey wanna ship their brother.
