You were on mission with Denki. You both had similar quirks. Denki had Electrification quirk while yours was Lightning. He could hack into devices while you could use your quirk to hack into human nervous system using Electro Magnetic Pulses or EMP & effectively manipulate the nervous system & flow of hormones like dopamine, serotonin, endorphins, oxytocin, etc. . You & Denki had history together, being friends with benefits for some long time before he started dating Jirou in college at UA. Being similar quirk users, you & Denki used to kiss each other to 'recharge' each other's quirks. When you also joined college at UA, you & Denki couldn't even fight off each other during matches by simply using your quirks, since you both just absorbed the attack & just got stronger. The teachers & audience would groan in exasperation seeing you both just play around the arena during matches, only to decide the winner at last using rock-paper-scissor. . Jirou recently started dating Denki, as she liked him & didn't want to loose him to you. She knew about your past with Denki. Everyone knew at this point. So she was secretly wary of you even though you were included in the friends circle by now. The girls knew through Jirou & the boys knew already since Denki was a flirt & he'd sneak into your room before he decided to get serious with Jirou. . You & the others were on a mission. During which Denki uses up his quirk since his hacking abilities were the most important during this mission. He was accompanied by you since yours was similar quirk & they needed all the emitter-type quirks. Others were keeping tabs on the mission back from the safe house monitoring room. Suddenly you realize villains approaching & Denki being out of commission was a liability. You knew you couldn't wait for to him recharge on his own. Just then Hawks orders through comms to recharge Denki & get out of the place before the villains surround it. . You had no choice but to kiss Denki giving him a boost of recharge him & drag him out of there. Denki was too occupied in the mission adrenaline rush to comprehend that his old flame just kissed him. It was like second nature to him to have you give him a recharging kiss, that he didn't think anything of it. Until you both reached back at the base & saw the face of Jirou. She knew it was an order from the pros & there was no other choice than to 'recharge' Denki, but the fact that you already had history with her boyfriend didn't make her feel any better. . The Bakusquad was on edge knowing things are about to get heated soon. Bakugo was scowling waiting for his Sparky best friend & you the newbie to return. Dekusquad was concerned about the confrontation that would happen between Jirou & you. Monoma & his gang were just watching hoping for some drama but also wanted things to smooth out. The faces of others were also tense as everyone anticipated her reaction to seeing you & Denki. You enter with Denki & feel sharp gazes & concerned looks. You were able to recharge Denki just enough to get back to the safe house & not fully, due to the critical time constraints. You were holding him up since he was about to pass out again. His best friends Bakugo & Kirishima rushed to get him inside.
