From Canis Major Scanlations:

Mizushima, a florist shop staff, wanders into a big mansion’s garden because he’s attracted to the flowers there. Fujisawa, who lives alone in that mansion, suddenly came to request for a flower arrangement from him. Upon arriving at Fujisawa’s mansion again, Mizushima is caressed by him…

Is he only playing around with Mizushima? What are his true intentions?
