Sweet date with Sugar

Protagonist, who was called by Sugar, noticed familiar parts on Sugar as soon as he arrived.

"Recently on the Ark, I tried attaching new parts that are popular with Nikke..."

The Protagonist looked everywhere. In fact, quite a few Nikkes were equipped with similar parts. Most of them seemed to be on dates.

“So, what does it look like?”
“I’m used to it.”
" what?! "

The Protagonist, who had inadvertently told everything without hiding anything, was also surprised when Sugar was surprised.
Because he realized too late that he would not be able to avoid disciplinary action if Sugar found out about the previous 'top secret operation'.

“...I loved it so much that I experienced it to the point where I was used to it!”

The Protagonist managed to correct his own mistake.
...But he made another mistake at the same time...

“You like this...?”

Sugar's 'special parts' grew bigger and stronger.
Before he had time to react, she came closer in an instant, pushing the Protagonist against the wall.
Protagonist couldn't help but notice what Sugar was going to do. Anis also did the same thing on that island.

“Is it time to kiss?”
“Oh... maybe...?”

The kiss with Sugar again tasted like coffee, but along the way, a 'special milk' flavor was added from the bottom.
Anyway, it was sweet.

“How did it taste?”
“It tasted like sugar.”

...He ended up eating three more times.
And, together with Sugar, he got to clean up the 'special milk' that was all over the place.
In fact, about half of them were eruptions from other Nikkes nearby.

After some time, 'Sugar Milk Coffee' was added to Cafe Sweety's Protagonist-only menu.
The coffee price displayed on the menu was 'three times in a row', a sign whose meaning I did not understand.
But Protagonist soon found himself paying for coffee 'nine times in a row' every time he visited Cafe Sweety, because 'Milk Milk Coffee' and 'Frima Milk Coffee' were soon added to the special menu as well.

“Is it time to kiss?”
“Then, the same goes for kissing three times in a row.”

It became ‘twelve times in a row’.
