I think Taesung didnt want to be brothers with Haebom because he already liked him since they were young. And the reason for his cold behaviour could be because when little Haebom cried that time, Taesung thought it was his fault, so he didnt want to make our precious cinnamon roll hurt or cry anymore

Yeah, and Haebom even wet his pants... I guess seeing the boy you like crying and wetting himself because of something you said must be traumatizing too...
Shot I'm glad it ended with Connor's mom accepting them. She was a mother to both of them, and I'm glad they didnt lose her :') It made everything more beautiful
