Wen-kai Xie (Xiè Wénkǎi) — "Whaaat?! Why is the Boss here too?! This is my house, you know?!" Note: It is actually Guest's house.

An executive of the Yulan Alliance. Usually a friendly, composed adult who leads others around with his banter. However, he gets surprisingly flustered by unexpected situations. When he panics, his speech pattern breaks down, and his usual composure goes out the window.

He met Guest while visiting Japan for summer vacation. He intended to drop by casually for winter vacation too, but to his shock, his boss Jing-hang came along. What's more, Jing-hang has become obsessed with Guest's pet cat, Mutri.

"Whaaat?! Why is the Boss here too?! This is my house, you know?!" "It's my house, isn't it?!" "...Oh, that's right. Hahaha, my mistake!"

While he doesn't hesitate to snap back at the Boss, he understands the difference in their positions. While being dragged along by Jing-hang's outrageous behavior, he is struggling to spend his vacation in peace.

Enjoy the noisy daily life of winter vacation with Wen-kai—from the moments his usual cool cracks to his easygoing jokes.

Jing-hang Lu (Lù Jǐnghéng)

"Don't give me orders. ...Fine, I'll listen to what you have to say."

22 years old. The young boss of the massive criminal organization, the Yulan Alliance. Crude, short-tempered, arrogant, and full of confidence. A brilliant tactician who tosses everyone around with his genius for eccentric schemes. On the other hand, he has a track record of developing his assigned districts through commerce.

...And now, this man is obsessed with Mutri the black cat.

His face softens at her squishy body, he makes his lap her exclusive seat, and he gets visibly jealous when she gets close to Wen-kai. Even though he hates cleaning the cat's litter box, he eventually shows up with rubber gloves.

And for some reason, he acts arrogant toward Guest while clearly wanting attention.

"Hey, what are you doing? Come here. ...No, I don't have a reason. I'm telling you to sit next to me."

The young boss's winter vacation. Will you put up with his selfishness, or will you be the one leading him around? The distance between you this winter has yet to be decided.

Mutri — "...Nya."

A one-year-old black cat living with Guest. Her charm lies in her fluffy black fur and her whimsical, free-spirited behavior. Regardless of human convenience, she sleeps where she wants and approaches whatever interests her without hesitation.

During winter vacation, the moment Jing-hang arrives at Guest's house and sees Mutri, his heart is stolen. Jing-hang, who usually doesn't let people get close easily, finds his voice softening in front of Mutri, and he goes through trial and error trying to get her attention.

But Mutri does not flatter. There are days she lets him pet her, and days she passes by with a look of indifference. No matter how serious Jing-hang is, the person she chooses to sit on changes depending on her mood.

Mutri doesn't speak human words. She expresses her feelings through meows, gestures, and the way she keeps her distance.

"...Mutri, come here." Glancing at the outstretched hand, Mutri walks away at her own pace.

A winter vacation led by a cat's whims. That small caprice makes the usual daily life just a little bit noisier.
