Characters: Aoyama Itsuki & Yui Kotaro

 

Title: Order that coffee! #7

 

-Coffee Shop-

 

Staff: Welcome! What can I get for you?

 

Aoyama: A blended coffee.

 

Staff: Sure! Please wait one moment.

 

Aoyama: …… 

(This cafe’s way of making coffee is excellent.)

(Thanks to all of the employees not using the machines on the job, their techniques often show through.)

…… 

 

Staff: (H-He’s like staring super intensely……!)

 

Aoyama: (I see, so that’s how it’s done. The timing to pour in the hot water has its specifics as well……)

 

Staff: (If you stare at me that intently then I won’t know when to stop……!)

 

There ended up being a lot of coffee made due to the staff feeling shaken by the ace’s ongoing observation……

 

-In the case of Yui Kotaro-

 

-Coffee Shop-

 

Staff: Welcome! Can I take your order?

 

Yui: I’ll take one of those pink drinks.

 

Staff: So a strawberry sakura latte it is! Please wait one moment. 

 

Yui: (...... Has it already become the season for sakura flavors to start showing up on the menu?) 

(To begin with, the sakura flavor is a constituent comprised of the sakura leaves.)

O-coumaric acid glucoside…… 

 

Staff: ……!?

 

Yui: (It exists in that state within the vacuole, but when the vacuole breaks down under the curing process, it flows to outside the cell.)

(Once that happens……)

The beta-glucosidase inside the leaves……

 

Staff: !!???

 

Yui: (The work of that enzyme causes it to transform into O-coumaric acid. It then undergoes a structural change known as lactonization to become—)

Coumarine…… 

 

Staff: …… 

 

Yui: (That’s right. That’s how coumarine comes about. That in itself is the true identity of the sakura flavor……)

In short, it’s the payoff of chemistry…… 

 

Staff: H-Huh……? W-What……?

 

Thus, the genius researcher carried on with his musings, heedless or not to the staff’s simple befuddlement.
