😋According to your needs, I recommend the military-spy novel, The Strongest Babysitter Soldier King, to you. The male protagonist, Ma Fangnan, was once an all-powerful iron-blooded soldier king. Now, he had transformed into a super nanny father, reflecting three elements of humor, warmth, and sweetness in his daughter. There were sad elements in the story, but at the same time, the ending was very warm. I believe that you will definitely like this kind of novel where the male lead is not only invincible but also heart-warming! I hope you like my recommendation.😗
