This is inspired by true events, sadly. There have been allusions to it in the past, gotta write it now.
At that very moment he would have paid all his life's savings to have someone shoot him in the head, no questions ask. The savings in question wasn't much but surely there was a cheap murderer for hire. Pyschopaths maybe people who liked killing people for fun. Do what you enjoy doing the most and get paid on the side. He should have considered the possibility before leaving the house. Now he was stuck. He was drenched with sweat, the cool breeze made him shiver.

Never again. Never fucking again.

She sat a few seats over, the furthest one that was unoccupied. She gave him glances, uncertain and quick, he could see that in the periphery as he focused on pretending to read the ebook. Heart racing, ears pounding, eyes clouding. Dear gods! What an ass he had made of himself.

The story was short: a girl he had met on the bus stop, had started talking to. They hung out in the free time at the coaching center they were taking different courses in. His friends found out about it. Over one lunch, they dragged him away from her, told him he was not into it. And he pretended to not know her thereon. Twice.

Apologize. That's what other friends, non-assholes had told him. What for. And say what. My friends think you're not good enough for me. I'm not that into you to begin with. We should stop...what, talking once every few days? No substance.

He didn't want to be in her place. The pain that she must have felt, the embarassment. She didn't show it, but he could imagine. He would be humiliated if he had been in his place, someone who didn't even talk to him properly 'rejecting' him for nothing, ignoring him like a nobody. When he'd not approached. The worst part was his ambivalence. If he liked her he'd apologize. He didn't want to set wrong expectations.

Was she gone? Was she gone? A quick glance, she had earphones on, her eyes closed hands clasped. Head rocking, lightly. Surely she was pretending like he was. What he would pay to get into her head and listen to the thoughts. It would be relieving if she were thinking about murdering him dismembering his limbs and throwing them in the four parts of the country. He deserved the hate. It was the disappointment and sadness from her that he feared.

She turned her head to him slowly, and peeked open an eye. He didn't look away. She turned her head right about instantly.

Just curse me, call me names please. Get me out of this self-imprisonment.

The bus stopped. Conductor shouted the location, it was for them. He rushed out of the bus before it had fully stopped, hurtled through the mass of students in Dillibazaar, ran by a group of PadmaKanya girls hooting. The nervous man didn't want to stop, to keep running and running and running till his legs gave away his heart stopped and he dropped dead was all he needed.

What a fiasco.
