There is nothing to introduce, the cp only has the title card (Senju Tobirama x Hatake Kakashi). Although it is a relatively unpopular character, the author really likes it. I can't write any long stories at the moment, but I have a lot of ideas for short stories, so I plan to write a lot of short stories and then make a summary.
Modern police academy if
Various original works if
Teacher x student…
All kinds of jokes and pitfalls, I'll fill them in slowly

Intention: I don't have any intention for the work, I just want to engage in my cp
