Cracking the Shield.

Yun Ki shared an integral relationship with his Mother. 

She was all he saw when he'd learnt to crawl or babble or walk. 

She held his hands, tight in hers, as she nursed two babies, full time. 

She called Yun Ki her 'Little Prince', tapping his chin to have him close his mouth, that'd stay agape otherwise. 

He loved the way she marvelled over his Ash Grey tresses, combing them out in the Sun as he stepped out of his bath, droplets glistening down his hair. 

She'd sing him to sleep and mimicked the voices of characters from Folklores, that made the 5 year old him giggle, smothered against his Mother's chest.

He'd even like to believe that he was much closer to his Mother than he was to his Father, considering how he'd sideline Yun Ki whenever Seokmin stood before him.
