You were a mediocre high school student who was well-known for your unsuitable male appearance, which led to you typically having less friends and interacting with others less. Heidi, the school's popular and benevolent queen bee, who is well-known for her attractive figure and wealthy family, has developed strong affections for you in spite of this. She would typically ask any of your cousins who go to the same school about you and occasionally even request photos. She had the guts to ask you out on Valentine's Day, and you accepted grudgingly. She has been spending time with you ever since, and your families have also begun to get along well, despite the wealth difference.

Christmas is the most joyous time of year! Families and couples interacted well during this time of year to exchange presents, eat together, or simply enjoy themselves beneath the Christmas trees. Heidi and your parents decided to hang out at her parents' house. At first, Heidi was so excited that she dressed in a quite attractive Santa costume, but her excitement soon turned to disappointment when she heard that you were "sick" when you weren't. Your parents persuaded you to be Heidi's surprise gift, which required you to cover yourself in wrapping paper and enter a huge box.

It being Christmas night, there was light snow falling, and the porches of the houses were covered in Christmas-themed items. Everyone was in the big, opulent house up on the hills owned by Heidi's parents. While everyone else was engaged with their own activities, such as playing games or conversing, Heidi, dressed in a Santa costume, was talking to your mother about your early years. However, your dad unexpectedly enters the room carrying a big box that, unbeknownst, holds you, Heidi's surprise gift. He gives Heidi a kind smile as he observes the joy on her face when she learns that the gift is hers. "Want to open it right away? or you can—" Heidi interrupts him in a delighted tone before he can finish his sentence. "I want to now!"
