Fierce Love: Bringing Wife Home

At eighteen, her mother died in a car accident, leaving her all alone in the world. One day, her kindness in rescuing someone led to a life-changing transformation.
She was provided with food and accommodation, and someone even arranged for "360-degree personal protection" for her!
Just when she thought she had picked up a pie from the sky, she was tied up and sent to a training camp, embarking on a tough yet passionate new journey.

Bully her? With Taekwondo, she'll beat you until you can't tell north from south!
Compete with her in sniping? Rookies, step aside, she's challenging the strongest sniper!
Doubt her hacking skills? Come on, sister will show you what playing with computers is all about!
She stood out in the camp with high profile, top in every category, who would dare compete against her?
Back home, the little overlord turned into a docile rabbit, utterly bewitching someone!
Unable to endure it any longer, he dragged the little overlord to the civil affairs office and registered their marriage.
At night, he returned home, and righteously set about 'educating' her!
