I dreamed that I was a guy, and quite a stereotypical anime-style scary third-rate bully with hair sticking out in all directions (I even remember that it was black!). For some time, I was dating an incredibly cute girl, who then dumped me for some handsome guy, who actually turned out to be a decent person, someone I would have befriended in real life (but he wouldn't with me!).
Then the events jump forward, and I meet my "first love" again. She already has a son growing up with that guy, but she's with someone else because her beloved disappeared without a trace. At this time, I already have some superpowers, and I use them to search for that handsome guy. I remember that I expected to find him in the arms of another woman, so I could win the young mother back for myself, but it turned out that he had protected a stranger (I remember her name was Diana) a few years ago, which led to him being captured in another world, where he was sold into slavery.
The events of me kicking the butts of all the scoundrels didn't stick in my memory, but I do remember a confrontation in which my beloved, her current partner, her true love, and Diana all participated. Since I didn't have a chance with the young mother, I had to ask my boss for help (by the way, she was the principal of the school where I work) to create false memories, so that it would seem that the handsome guy, while saving Diana, got into an accident, lost his memory, and she started taking care of him, and they eventually grew closer. Then they all decided what to do next, but I didn't participate in this mess because I didn't care about being with the cute girl anyway. In the end, the cute girl and the handsome guy reconciled and continued to raise their child, the second guy just left, and Diana started showing interest in me, and I'm not against it.
Then the events go far back into the past, where I'm in university, and the same cute girl just broke up with me. As usual, I sat down at the back desk to sleep, but soon a tanned blonde (who wasn't in my group) sat next to me. I was alarmed that out of everyone, only I didn't know her, and she was scared that I had noticed her. Then a portal appeared in the classroom, and monsters appeared, which, as it turned out, only I and the tanned blonde could see. The blonde pulled a sword out of nowhere and was about to fight the monsters, but I was in a bad mood because of the heartbreak, and everything annoyed me, so I stood up, and two clubs materialized in my hands, which I didn't pay attention to, and I single-handedly beat them all with a few blows. And my new acquaintance told me that I was an unusual person and offered me to work for her organization (presumably the same one where my principal was the boss).
