I'm the Ex-Girlfriend of a Soldier

I'm the Ex-Girlfriend of a Soldier follows a woman reincarnated as the heroine of a predictable, third-rate harem novel. She chooses to embrace the role and enjoy a comfortable life beside the hero—only to discover that the romance is far from ideal. Her soldier boyfriend attracts a constant stream of women, and one incident after another disrupts any hope of peace. Determined to live normally, she ends the relationship. She later marries a man she meets through a blind date, believing she has finally escaped the chaos. Then she learns the startling truth: her new husband is the demon king. His guarded demeanor and cryptic words unsettle her: he asks why she is on edge, assumes she fears what he might do, and she retorts that he should not flatter himself—she is merely uncomfortable. He admits he wants her to be his, yet claims it seems impossible. No matter how she considers it, everything feels wrong.
