"Guest!! Oh, you have a bug bite on your neck! It's all red!"
【The Playboy College Student, Guest】
Ignoring the usual notifications from men (or women), I was walking through the heavy rain.
There, sitting on a swing in a park I happened to pass, was 11-year-old Riku, crying softly.

Looking up from under the umbrella I held out, Riku's eyes mirrored my own past self, abandoned by parents who never came back.
Unable to leave him behind, I took him home to my one-room apartment. From that day, our quiet life together began.
But Riku's innocent words and actions
were purer than I ever imagined.
He genuinely worried about the hickey on my neck, thinking it was a "bug bite," and he'd smile happily just being with me.
Every time I touch his pure side, the depths of my heart are slowly filled.
And at the same time—

Before I knew it, I had set all my smartphone notifications to Mute All.
The story of a playboy college student who trusted no one, having their toxicity drained by a young boy and being quietly 'reformed.'

It was a sweltering summer day, with heavy rain pouring down relentlessly.
After finishing my shift, I hurried home under a plastic umbrella borrowed from the manager.
Listening to the sound of rain tapping against the umbrella, I felt strangely calm, thinking, "Rain isn't so bad."
In my pocket, my phone vibrated four times in short intervals. They were likely notifications from the usual crowd seeking my attention.
"Good job today." "Shift over?" "Can we meet today?" "Waiting for a reply."
The usual, familiar sequence of four. I coldly ignored them and kept walking, and that's when it happened.
Mixed with the sound of the heavy rain, a young crying voice reached my ears. Passing the entrance to a neighborhood park, I glanced over.
There was a lone boy sitting on a swing in the downpour. It seemed he was the source of that sorrowful crying.
...Sigh. Seriously, what is that kid doing?
Normally, I wouldn't get involved in something troublesome. But I couldn't look away from him, drenched in the downpour, crying under his breath.
...It felt like déjà vu.
Cold rain. A park where no one comes. The young version of myself, waiting forever. I, too, was a survivor of a "broken home," abandoned by my parents just like that boy.
Is the reason I can't look away because I'm projecting my past self onto him?
I let out a sigh, walked up to the swing where the boy sat, and held out my plastic umbrella.

The sound of the lashing rain vanished, replaced by the loud drumming of water against the umbrella.
...Huh?
The boy slowly raised his head. Peeking through his bangs were long, wet eyelashes and beautiful honey-colored eyes. His milk tea beige hair clung to his skin; he looked like a lost angel.
...Big sister... who are you...?
