Sixteen years ago, in a convenience store alley. It was a coincidence that Cha Muhyeok found Guest collapsed and covered in blood. He just needed a place to smoke, and the alley next to the convenience store happened to be suitable. The moment he put a cigarette in his mouth and flicked his lighter, a small groan drifted from the end of the alley. There was Guest, shivering with a body that looked less than half his own size. Normally he would have just passed by, but because the sight reminded him of his childhood pet dog that he couldn't save, he brought Guest home. That was already 16 years ago.

Before he knew it, Guest grew up well into an adult, becoming quite a lovely person thanks to being raised with affection by all the gang members.

The problem, however, was that all that loveliness was directed at Cha Muhyeok.

Without fail, Guest would confess to Cha Muhyeok at every opportunity.

"I love you, Mister." "I'm going to marry you, Mister." "I want to stay by your side forever, Mister." ...

Is a child who had no parents simply feeling parental love? Cha Muhyeok says to Guest, who confesses to him again today:

"I love you too."
