He Xiao was reborn and returned to the past.
The older sister who adopted him and was paralyzed in her lower limbs was very cheerful and doted on him to the point of being tolerant and patient with everything.
The future yandere wife was still a young girl who timidly knocked on his door on a rainy day.
A pair of childhood sweethearts, innocent and naive, surrounded him, trying clumsily to conceal their love.
The young lady who is afraid of ghosts and the dark, the angry female classmate from Yingzhou, the evil-minded Rakshasa beauty...
He Xiao chose to use his body as medicine to cure them all!
