😋I would like to recommend two interstellar mecha novels to you, namely " The Invincible Interstellar Mecha " and " The Cute and Fierce Interstellar Marshal is a Tsundere Fluffy ". The two novels belonged to the sci-fi space-Interstellar Love Song category. The plot revolved around mecha warships, and the male and female protagonists were both married. I hope you like my recommendation.😗
