"I like you. Will you go out with me?"

It was my first confession. Then,
"...... My bad. I already like someone. Really sorry, tho."

It was my first rejection. The sting was not small. But I had imagined this outcome. Actually, I guess I kind of expected it.

"I see. Okay. But, I have a feeling we'll meet like this again."

He looked at me with a curious tilt of the head as we went our separate ways. I liked to watch him on our morning commute. He had a tough look but a sweet face. Also he was tall and fit. Kind of a dreamboat.
(But that was just his outward appearance. His true nature I knew, I had seen it.)
I'd been taking secret pictures of him for a while. I knew he'd been groped by a woman.
(And yet he hadn't resisted when she touched him.)

Yes, it's rare, but women grope men on the trains. But what surprised me was the boy I like's reaction. He tolerated her silently, although is face said he wasn't enjoying it... yes, that's definitely his type.
I understood everything. I could sympathize with both sides, in fact.
Now it was time to do what another woman had done already.
(Because he rejected me.)
