"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.)
