[Gintama] A Gentle Breeze and Homecoming

It was a bright, sunny morning when the Shinsengumi took in an amnesiac girl of unknown identity. Meanwhile, just as the Yorozuya boss finally won his freedom after being thrown in jail by his childhood friend and classmate, whose intelligence was truly something else, he unexpectedly discovered... Some silver-haired guy (shouting himself hoarse): "That's my aunt! My aunt!" Everyone (after comparing the two): "...Who do you think you're fooling?!" The girl... remained completely bewildered and out of the loop. Back when Gintoki was still young and naive, he had once been curious about her real age. "Auntie, how old are you, anyway?" He Feng ruffled his silver hair and smiled faintly. "Of course I'm eternally nineteen, so hurry up and call me big sister." "...Okay, Auntie. Got it, Auntie." ☆Before You Read☆ ① The author's imagination runs a little wild. ② The romance is unwaveringly Gintoki → He Feng. ③ The usual style: girls' love is the best. ④ A raising-the-love-interest story, with a somewhat complicated timeline. If you dislike a female lead who's an old monster (hey!), proceed with caution.
