[Tokyo Revengers] Delinquent

As a girl in the middle of adolescence, I never know what to expect. Like the day I woke up in a juvenile detention center. Like receiving a pile of embarrassing love letters from the same person, signed by Sano Shinichiro, who claimed to be my boyfriend. Worried I might be mistreated in there, Sano asked his younger brother, who had also been locked up for getting into trouble, to look after me. He said Izana was great at comforting people and told me to go to him whenever I was feeling down. But as time went on, I realized Izana was even more emotionally unstable than I was. Izana had a group of friends. He said that if I wanted friends, he could beat a few people up and get me some. After all, that's how he'd gotten his own friends, if you could call them that. I had a little first-aid kit, given to me by one of the staff members in charge of us. But I hardly ever used it on myself. Most of the time, I used it on Izana. Maybe word got around that I had a first-aid kit, because before long, Izana's friends started coming to me for bandages too. The first person I saw after getting out was Sano. He wasn't what I'd expected. He was quite handsome, and didn't look like someone who could write such toe-curlingly embarrassing letters. I thought he would hug me. Instead, he suddenly bent over and bowed to me at a perfect 90 degrees. "I'm sorry! I lied! I'm not actually Miss Kasai's boyfriend!" As if someone had flipped my fainting switch, my vision suddenly went black before I could ask him why. Just before I lost consciousness completely, I heard a cold, mechanical electronic voice by my ear. [Trigger condition fulfilled] [Updating your map] My name is Kasai Natsuki. I found myself sitting in a classroom. As you can see, I'm a first-year high school student. I transmigrated into the past, before I entered juvenile detention. I ran into Sano. This Sano turned out to be my secret crush. Theme: Striving through hardship
