Tutor Reborn's Yun Gang fanfic
The setting is a time point in the future after the war
Tsunayoshi has a bit of PTSD due to the future battle, so he can be a bit clingy (it's not serious, I don't know much about the illness, so please forgive me if I'm wrong)
It is 1827 of all27 soup base
ooc is my fault
