[Gintama] Teacher Shoyo's Happy Everyday

It is about Shoyo being reborn ten years later, only to discover that a long time has passed and his students are scattered far and wide. He thinks, "Wouldn't it be pretty awful to die without a word, then suddenly show up again?" So he feels a little guilty and doesn't dare reveal who he is right away. He gets involved in the events of Gintama as a side character, but his students see through him with ease. In the end, he gets to cuddle up with his students. Shoyo is the bottom. He has the feel of a mature man (a thousand years old, perhaps?) who isn't tsundere and won't blush just because he holds someone's hand or sleeps beside them. If he wanted to be the top, he could top them all, but he loves spoiling them too much, so he lets it go. The tops are Gintoki, Takasugi, and Katsura. Oboro and Utsuro have roles, but nothing substantial. There are non-romantic emotional storylines involving Shinpachi, Kagura, Otae, Hasegawa, and Kyoshiro toward Shoyo, and Omi Ichi toward Utsuro. There are elements of Hijikata and Mitsuba, Kawakami Bansai and Tsuu, and Utsuro and Oboro. No Gin and Saru pairing (though there are some emotional scenes involving Saru). The demons at the Rengoku-kan, Tsukuyo's master, Omi Ichi, Kamatari, Kouka, and Kawakami all come back from the dead. The plot follows the anime's chronology. He has feelings for all the tops. Katsura is my personal favorite for the romance, and I plan to write a separate story for the other characters' romantic scenes later. Theme: Putting Utsuro through the wringer (?)
