Kissing
Katsuki Bakugo and Mei Hatsume were in the middle of the hallways of UA High in the middle of one of their favorite pastimes; kissing. The two had been together for months, and spent every moment they could together. People were shocked when they found out that Bakugo had a girlfriend, but given his improving attitude and being closer to an expert mechanic, they came to terms with it and some even became friends with Hatsume. But right now, it was all about Bakugo and Hatsume.
For Bakugo, kissing Hatsume was like a rush of euphoria. The feeling of Hatsume's soft pink lips on his own made him feel like he was completely devoid of negative emotions. He never thought that such a simple act can leave a lasting effect. Bakugo was known to get angry and stressed at the speed of sound, which would all immediately go away the minute the taste of Hatsume's lips entered his mouth. He knew it sounded shallow, and there were plenty of other things that he liked about her, but kissing Hatsume was one of his favorite things to do with her.
For Hatsume, kissing Bakugo felt like a rush of support. Whenever she and Bakugo kiss, she feels them getting closer and closer. Mei has always been a lonely child, and this did not improve much in her teenage years. Hatsume loved the closeness that she and Bakugo had, and to her, kissing made that closeness increase and become stronger. But she also had moments where making her 'babies' leaves her mind, and her mind fills with thoughts of happiness and Bakugo.
When their lips parted, the two smiled at each other with as much warmness as they both could muster. Before they could get back to kissing, Kirishima, one of Bakugo's friends, called out to him.
"Yo Bakugo! Class is about to start!" Kirishima called before turning the other way and jogging to class. Bakugo was about to snap at Kirishima, but Hatsume kissed him on the cheek and skipped back to the workshop. Bakugo gave a tiny smile in Hatsume's direction before running to class.
