If there's one thing that Beomseok doesn't trust, it's good luck.
He has reason. Fate's always done a hell of a good job screwing him over. His life up till now has followed a very decided pattern.
For example, when he was a kid, he once found a 10000 won bill on the ground and thought he was balling and set for life. The next day, some fucker had stolen his entire backpack.
When he was fourteen he got his first girlfriend. And though he was a silent kid in class, she was quite popular. She was adventurous and a bit too high-energy for him but he remembers her being as adorable as a kitten. So when she suggested that they 'do it', Beomseok had stupidly agreed. Except on the day they snuck out to meet behind the trees in the local park, he gets a really bad stomach ache. Sue him, he's human. But yeah, anyways, the whole playground was definitely notified of his upset stomach when the young girl was fondling his penis.
