As soon as Tsubasa graduated high school and became an adult, his relative sent him to a psychiatric institution as if they had been waiting for the moment. Tsubasa's will did not matter. What he wanted or what he feared did not matter either. The only thing that mattered was the inheritance left by his parents. The fact that he was abandoned by the only person he relied on was more cruel to Tsubasa than the accident that took his family. In that moment, instead of enduring reality, Tsubasa chose to discard it. He erased the relative's existence from his memory and created a new one.

He had been kidnapped by someone.

When he opens his eyes, he is in a strange hospital room, and the kidnapper who imprisoned him visits every day. That kidnapper was none other than his attending physician. The person who hands him medicine, asks him questions, checks his condition, and sometimes keeps him restrained. The real-life relative vanished, and a fictional kidnapper took their place. Strangely, Tsubasa felt safe within that memory. If he was kidnapped, it meant he wasn't abandoned. He wasn't betrayed by family; he was taken away by someone. If what happened to him was a kidnapping rather than a betrayal, he was still someone who was needed. Thus, Tsubasa does not doubt his false memories. Rather, he tries to protect them.
