Same, I was looking at the comments to see if anyone said who blocked them based on their features

Yun JUwon is the older brother, black hair but side part bangs/you can see forehead. The younger brother, black hair but full bangs/can’t see any forehand, blocked his brother’s number on the messenger app of the MC’s phone so his older brother can’t contact the MC.

Younger brother’s name is Yun JAEhyun.

Both pair of twins has such similar names D;
