[Anime Crossover] The Gentleman License

On my twenty-second birthday, I had never been in a relationship, so I prayed to God for a boyfriend. And then... God gave me a system called "Koukou" and a stack of gentleman's licenses. From then on... The malice of the world fell deeply in love with me (and my licenses). Whenever I go home, someone eagerly asks me to Koukou. When I take the train to work, there's always some strange creature nearby hoping to ask me out for Koukou. I finally find a part-time job, and that minor isn't here to get me to teach him Koukou, is he? Me: Are you kidding me?! What on earth is Koukou? System: Support the crackdown! Destroy Neon! #Friend, do you know what it means to recommend something you love? # #A world only experienced drivers understand# #Is there anything wrong with being a quiet gentleman? # #Japan can never become the purest country in the world# Reader's guide: 1. The setting is based on A Boring World Where the Concept of Dirty Jokes Doesn't Exist. 2. A crossover with multiple anime series, mainly Katekyo Hitman Reborn!, Vampire Knight, The Prince of Tennis, and Dirty Jokes. 3. The heroine's main job is as a teacher, and her side job is as a salesperson. Supposedly, she's going to replace every [beep] anime's male lead. 4. The author is pure! The author is pure! The author is pure!
