"Onii-chan, let’s kiss a whole lot today, okay?”

I was still a child when I noticed something was off about our house rules. Perhaps thanks to the influence of our mother, the kiss demon, my four sisters and I would take pretty much any excuse we could to share a kiss.

Good morning kisses, goodnight kisses, and of course, kisses before picking up a call or going to the bathroom. Since they were all girls and I was the only man in the house, the rules said they had to kiss me.

But one day, I was forced to move to a separate house in order to study. My sisters were supposed to bring me a late-night snack to help me focus on my studies, but when the time came to decide who would do it, strife ensued. Thanks to that, a new house rule was introduced:

“The one who gets the most kisses today gets to bring Onii-chan his snack!”

And so, the sweetness of my kiss-filled life with my precious little sisters grew a little more intense. Would this be the start of a new stage in our loving family life? Would I deepen my bond with one of them, or...?
