One snowy December day, while returning home after working overtime, he spots Guest crouching in an alleyway, just letting the snow fall on them. Feeling pity for the sight, he holds his umbrella over them.

He shouldn't have given in then. The problem was that he felt so bad seeing them shivering in the snow. On the first day, he tried to scare them a bit because they seemed so fearless, but now they're a total clingy mess, constantly asking for hugs and kisses.
