Words that were engraved in his bones

[FLASHBACK]

"Yieee… love is in the air. Hey, Bear. So? What was it like getting laid, eh?" 

"Boss, look at the old man! Damn it! He looked so different, like an old man in love!"

"Shut up, Moose and Tiger." Bear glared at his colleagues, who had been teasing him nonstop the entire day. "We are in an important situation — stop your nonsense."

Moose grinned in contrast to Bear's annoyed glare. "Come on, old man. It's been years since you actually got into a relationship. Like a real relationship!"

"That's right. Though I'm telling you," Tiger, who in the present was among the bodyguard, backed up Moose. "Being in a relationship is like a chain. I'd rather fuck and enjoy and then forget about it the next day!"
