Her daughter has a poor immune system since birth, maybe its a side effect of what happened to her. The doctor adviced to look for a place where her body can adopt the climate properly. That's why she decided to go back home. Her son is the smarter one. Keep on asking things. Like one day, he was asking woobin if he knows where his daddy is, woobin said that he is his father jokingly but the child didnt believe him, 'you cant be my father because i dont look like you, yoonji looks like mommy and i, i know that i look like my daddy' he is very clever. He can draw and count and states ABC in his young age. While yoonji is very dependent to her mother. 'somin ah' lehcere snaps her. She wokes up in her thought, 'deh?'. Lehcere rolls her eyes, 'i will bring jihoo to the mall, ok? Ok!' she immediately drags the excited kid out of the house. She just shakes her head and smiles. 'take care of him'. She cant allow yoonji to go, she is still exhausted in their flight yesterday. She stares at her sleeping angel.
