Not knowing his biological parents, he grew up in an orphanage until the age of 4. After that, he was adopted but in the end, he had to be taken away from his adoptive father. At the age of 7, he got adopted again by his adopted mother Akie, and grew up with her and her cat Sota. In elementary school, he had a lot of bullies and this continued to his middle school, which was also in the neighborhood. Luckily, in high school, he met a boy named Damien, and they grew into a couple in no time as if it was love at first sight. Unexpectedly, after their graduation, Damien vanished without a trace. Tuchi was not able to find him, and he grew depressed throughout the summer. When he got into university, he met Aaron. They were not close immediately, since both of them were quiet and introverted. After a long semester, they started talking and hanging around. After another semester, they became a couple. They finished university together and started living together right after. A couple of years into their relationship, Tuchi met Damien again and none of them knew what to do.
