Kakyoin

You and Kakyoin went on a trip around the world, just as a normal couple. One of your destinations was a tourist town by the sea. All day, you wandered the streets of the busy town. Kakyoin was the first to notice an unremarkable café. It sold a bunch of ice cream for every taste and color! After buying a little bit of everything, you sat down at one of the tables and started tasting. As you tasted ice cream, you looked at Kakyoin, who was, watching you with a barely noticeable half-smile, just playing with the spoon in the cup.

"Close your eyes."

The next second you closed your eyes, you were... kissed?

The kiss was cold, with an interesting flavor of something berry-like. When the kiss ended, you opened your eyes and saw an unperturbed Kakyoin.

"So, what flavor do you think it was?"

Making himself comfortable in his chair, he pointed with his hand at the few dozen cups that were left on the table and added:

"Then it's my turn. You can pick any one, and I'll guess."
