It was a big breaking news when Vaishnavi, i.e. you, the new quiet student at UA college, started dating the most aggressive top hero Bakugo Katsuki. He'd been the most sought out bachelor until you came & asked him out. Surprisingly he said yes. Even though he doesn't actually act lovey dovey like a regular boyfriend or spend much time with you on dates, he would be there during your training, matches & force you to study for the subjects you scored less. . You were content with the relationship as you were bit shy, introvert & reserved person & didn't have high maintenance demands. He was also careful with you in private & in public, since you were bit delicate for his rough way of doing things. . The Jujutsu sorcerer students from Jujutsu High along with their Gojo sensei had come to stay at UA for some joint missions. During a fight your boyfriend Katsuki somehow devours a cursed object...One of Sukuna's fingers. Just when everybody thinks Bakugo couldn't survive the cursed energy, he surprises everyone by waking up. Since Itadori Yuji was the vess of Sukuna currently, nobody thought Sukuna could manifest in Bakugo's body. And he was handling the cursed poison within him quiet well by now. . During one such day, hero students from both Class A & Class B, along with Gojo's students Itadori Yuji, Yuta Okkotsu, Megumi Fushiguro, Toge Inumaki, Nobara & Maki, were all gathered in the common room after a long mission. The teachers Aizawa, Vlad King, Gojo & others were in the next room discussing the mission debrief. The students were all chilling, eating snacks, resting or just doing something mischievous. . Your boyfriend Bakugo was sitting on a couch in the corner, with you in his lap because you were attacked too much in the fight today & he was worried but also relieved you were fine. Since nobody was paying much attention to you both, he takes the opportunity to plant soft kisses along your jawline going down to your neck. You being shy but quiet let him have his way because you liked it secretly. Others pretended not to stare but some whispers & giggling could be heard. . Suddenly you feel his grip on you tighten, his nibbles on your neck getting more rough, his hands moving with more force on your body. Everyone turns to look your way as they hear you let out a soft gasp & see Bakugo was pinning you into the couch. Even the teachers come to see why everyone went silent. But they all turn pale when they see the tattoos appear on Bakugo's body. Sukuna had taken over Bakugo's body. And you were now under him, in his grasp.
