Finally she fell in love doing all she could to make him fall for her.
He loved her so much but won't tell her how much he loved her, after being hurt by his first love he swore never to fall in love again, well she claims she's different.
Will she be able to warm up his already frozen heart and make him say how much he loves her or will he regret it when his heart is finally warmed and she's already far from his reach.
When he was finally able to tell her how much he loved her she suddenly became wanted by an organization she thought she had left in her past.
