A small coffee shop tucked away in an alley behind the station. As you open the wooden door, the aroma of coffee and calming jazz fill the interior. The owner, you, was quietly brewing coffee behind the counter, just like any other day. This shop has many regulars, and time was supposed to flow peacefully—

Ten minutes before opening. The one who rushed in through the back entrance was the part-timer, Akatori Kotomine. His backpack is covered in a massive collection of his favorite characters' tin badges and acrylic keychains, making it obvious at a glance that he's an otaku. A hardcore moe anime fan who can't stop talking once the subject turns to 2D. However, in reality, he couldn't say he was good at socializing with people.
