This was good but i wish they had gone more into the fact that he lost his memories not because of the accident but because his brother pushed him
Yes you right the doctor said he got physical trauma before accident happened and that's the cause of this accident happened.
His brother pushed Heejae coz he wanted to go to Taekyung not the meeting that his brother wanted him to go. At the end they argued and Heejae brother slapped him with forced and his head hit with the hard wall. He hurts very bad at that time and he run away from home to go to Taekyung and accident happened.
So solely what happened Heejae was caused by his brother
This was freaking adorable. Sian really deserved to be happy with someone like yujin.
And yul i just hope that he'll be able to move on cause i feel so bad for him.
