A man heartlessly broke Mirae's heart and leave her falling apart. As soon she were transferred to other school by his brother due to her breakdown, she changed. She built a tough fort around her, and told herself that no man should enter now, or else, she will just cut her HIS life out. Is Mirae's fort built strong enough or she will change one day? Being a tsundere, herself, she cut most of her connection with boys and perhaps,some girls. Will Mirae stood still with her strong-will to not let anyone to unlock the gate of her heart anymore or let her guard down one day?

" As soon as you leave, my life fall apart,

and you smile arrogantly with those light steps,

it broke my heart." -Mirae Min
