The man lives in his way, no one understands, no one understands him either.
Busy day, no work. There is only, learn, learn, learn keep learning, and just learn. All of that must have weighed on him, what was in Tae Hyun's head and mind just had to study and not think about anything else.
Unfortunately, it was Eun Ra who ruined all of Tae Hyun's expectations. Reminds how small and fierce what happened between her mother and her older brother.
Her grandmother passed away, the person who was so kind to her became so helpless just because of her mother and older brother's fight.
Until this moment Tae Hyun still doesn't know how exactly it happened, both of them shut their mouths roughly and there was no further investigation between Tae Jung and Su Ri who chose to remain silent.
Even at that time, Tae Hyun was too young to understand, the man only knew and remembered that his grandmother died, and it was only because of Si Ri and Tae Jung.
