It’s hard enough hiding my identity, but I’m also in charge of all sorts of annoying tasks: managing the protagonist’s diet, wardrobe, and house; coaxing and soothing the beta he loves.

It shouldn’t be possible, but that’s why I feel so f*cking awful, Secretary Kim.’ Will I be able to make it back alive…?”
