Akutagawa Ryunosuke is a 20-year-old mafioso, he was returning from the Port Mafia as usual. Standing at the traffic light and waiting for the light to turn green, he accidentally noticed a small flower shop on the corner.

However, then he saw a guy with silver hair and very beautiful purple-yellow eyes peeking out from behind the doors of the store. He took the flowers to the store because it was autumn outside and it was very cold. Akutagawa himself was wrapped in a warm coat.

Ryunosuke did not wait for the green light anymore, he turned around and headed straight for this strange, small but cute store.
