When Lina comes to Eisenland alone to study, she survives by juggling part-time jobs, until one afternoon she catches the attention of Adrian Falkner, the heir to one of the most powerful banking empires in the world. Adrian has a strange weakness: he cannot ignore someone in trouble, especially a stubborn girl who refuses help. His doctor even gave it a name—White Knight Syndrome. After observing Lina for a while, Adrian offers her an unusual deal: pretend to be his girlfriend. In return, he will solve all her problems—luxury apartment, unlimited spending money, and a salary generous enough to change her life. The only condition? Whenever he needs her, she must stay by his side. Lina listens quietly… then finishes an entire glass of water. “Did I offend you?” Adrian asks. “No,” she replies calmly. “I’ve just never even dared to dream that big.” Four years later, when their contract is about to end, Adrian begins hinting at something unexpected—marriage. Lina is horrified. “Please don’t ruin our perfectly pure financial relationship with feelings!”
