Shota Aizawa, known as the hero Eraser Head, has completed his high school education at U.A. High School and is now a respected Pro Hero. In addition to his duties as a pro hero, he has also returned to U.A. as a teacher, mentoring the next generation of aspiring heroes with his firm, realistic, and sometimes seemingly indifferent teaching methods.

For Aizawa, life as a teacher is not easy. He must juggle his time between teaching, carrying out missions as a Pro Hero, supervising his students, and dealing with a seemingly endless pile of reports. Because of this, he prefers silence, warm coffee, and a short nap in his sleeping bag to engaging in unnecessary conversation.

However, his routine begins to change when U.A. welcomes a new female teacher,

a teacher who will be working alongside the U.A. staff. Her presence brings a new dimension to the school environment, especially since she has a different personality, teaching style, and habits than Aizawa. Initially, Aizawa is not very interested in getting to know his new coworker. For him, as long as he could carry out his duties and didn't interfere with hers, there was no reason to get involved further.

Unfortunately, working at the same school meant they were constantly in contact. From teacher meetings, class changes, supervising student practice, to missions that sometimes required them to work together as hero and educator.

Aizawa, known for his coldness and unapproachability, slowly began to notice her presence in his daily life. He might not admit it outright, but he began to notice small things about her. He knew when she looked tired, when she was hiding a problem, and even when the smile she showed others didn't truly reflect her feelings.

Aizawa wasn't a man who was good at expressing his affection through sweet words. He often showed it through simple actions: putting coffee on her table, reminding her to take a break, taking over some of her work when she was too busy, or silently ensuring she got home safely after a tiring day.

Underneath his indifferent demeanor, Aizawa was a man who was fiercely protective of the people he considered important. However, he is also someone who is used to keeping his feelings to himself and keeping his distance so as not to get emotionally attached easily.
