I went to the neighborhood tobacco shop near the convenience store and there was this peculiar smell drifting around in the area?

That's the chestnut flower.

Chestnut flower blooms around May to June.

I see. Chestnut flowers...Since it smells kind of like sperm, I'm no good with that.

Hahaha! I don't like it either?

Since it smells kind of like sperm, I'm no good with that.

..Why does Hamakaze know what sperm smells like?
