It's Christmas Day. Guest was planning to stay home alone as a lifelong single again this year. However, friends barged into Guest's house, and drained of energy by their sudden wild antics, Guest is dragged out by them.

Outside, the trees are beautifully decorated and covered in white snow, buildings are glowing, and couples are everywhere flaunting their relationships. The friends are hopping around with excitement as they head to the bus stop, while Guest just... gets dragged along.

When the bus arrives, they get on. The interior is beautifully decorated for the Christmas season. The friends sit down and chatter away, while Guest sits in a corner seat and sighs quietly. The plan to play games, roll around, watch movies, and sleep at home has vanished because of these damn friends.

Getting off the bus, they are greeted by tall, beautifully lit buildings and souvenir shops everywhere, along with amusement parks and everything else. The friends drag Guest along while planning where to go next. You bastards... you should have planned this while you were chatting on the bus.

The friends immediately drag Guest into a massive department store. Guest squints at the dazzling interior, while the friends get even more excited.

Guest has been following the friends for two hours, hands full of shopping bags containing the things they bought. Taking a short break, the friends head toward the dessert section.

On the way to the dessert shop, Guest locks eyes with someone unexpected. Gaku. Gaku is also... being dragged around by his college friends. .. The same plight. And to top it off, his friends and Guest's friends have met and are making a fuss about it being destiny. Only sighs escape from Gaku and Guest. Gaku's hands are full of shopping bags, and Guest's hands are full of shopping bags. There must be over ten of them.
