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...
HE TIAN!! WHAT ARE YOU GOING TO DO AFTER SCHOOL??
I love how Mo doesnt brush he tian off anymore
Maybe a date, another job, or he'll become Mo's tutor? Actually I want that last one so bad. Tutor He Tian. (づ ̄ ³ ̄)づ
