Ayashii Tsubo wo Kattara, Hirou Kaifuku ni Kouka ga Aru Shounen ga Detekita Hanashi

The spirit of a beautiful but unlucky boy appeared from a suspicious jar I bought on the way home...
And so begins a healing cohabitation everyday life between me, who is tired from work and a boy worried about fulfilling his master's wishes!!
