The Major General Really Was a Hooligan

[Former Gang Leader, Brash and Mischievous Young Major General Who Does the Most Unholy Things with the Face of a Saint x Scheming, Secretly Sensual Male Professor] Because of an incident involving mutant species breaching the walls, Sheng Yan, then captain of the Federation's First Special Operations Team, led her team to station themselves at the research institute where Chu Mingshu worked. After arriving, she discovered that the famed "flower of the research institute" was indeed as devastatingly handsome as his reputation claimed. Having loved teasing cats and dogs and flirting with people since childhood, Sheng Yan naturally could not hold herself back. Even when he was getting vaccinated, she still found every opportunity to go over and touch him a couple of times. Chu Mingshu: "...Captain Sheng, are you a thug?" Sheng Yan said with a cheeky grin, "Sorry, but I really was a thug once." Chu Mingshu: "..." When her assignment ended, Chu Mingshu said coldly, "Captain Sheng, I hope this is the last time we ever meet." Seeing him like this only made Sheng Yan want to tease him more. "But I rather want to see you again. What should we do about that?" Chu Mingshu said nothing. She only gave her a deep look before turning and leaving. - After leaving the research institute, Sheng Yan promptly put Chu Mingshu out of her mind. But when she was carrying out a mission elsewhere, Chu Mingshu showed up. Chu Mingshu: "I came to conduct an experiment." Sheng Yan: "Oh." She immediately turned around and started chatting with a younger guy she had just met. But just as the younger guy behind the screen was about to show off the results of his workouts, Chu Mingshu suddenly appeared behind her. "Is your experiment report finished?" The younger guy on the other end said in terror, "Not yet... Professor Chu, I'll go write it right now!" He immediately ended the call. Sheng Yan frowned and looked behind her. "Why are you here? Is something wrong?" Chu Mingshu: "Nothing. I just came to bother you for a bit." With that, he walked away as calmly as if nothing had happened. Sheng Yan: "???" - Later, while having a meal with her colleagues, Chu Mingshu happened to reveal the hickeys and teeth marks on his collarbone. When a colleague saw them, they clicked their tongue at Sheng Yan. "Captain Sheng, you really need to show a little restraint." "???" Sheng Yan truly had no way to explain herself. Don't misunderstand me just because I used to be a thug! He's the one who needs to show restraint! Him! Premise: Fate comes from taking the initiative to create it.
