Her memory was so painful that he just blocked her out altogether to spare him the pain. Nagito wants to be accepted. Now, this may seem obvious, looking at the nice atmosphere his dream world had, but it struck me in the scene where he starts rambling and cornering Fuyuhiko. In other media his classmates shunned him out and were outright mean to him for his weird opinions and outbursts. We can say, then, that Nagito was really hurt by their behavior. Nagito wants to be accepted, but not at the expense of who he is.
At Hope's Peak Academy, a school full of extraordinarily talented individuals, Nagito Komaeda is an ordinary boy with no special traits or interesting skills to speak of—except for his incredible unluckiness. Just walking to school in the morning leads to a number of unfortunate accidents, which only escalate as the day goes on. Despite this, Komaeda leads a relatively normal life and is satisfied with his modest slice of happiness. But everything changes when a mysterious boy who declares himself the "Destroyer of the World" arrives to shatter this hopeless paradise.
Nagito Komaeda wakes up after experiencing death in the Neo World Program. What kind of world is he seeing and why did he wake up? Nagito appears to be in a strange world, including students who have been seen before as well as people who never existed. He is an ordinary boy with no Ultimate Luck, attending an ordinary school. Constrained by being the protagonist, he thinks that having a big talent would interrupt his happiness.
