It's the early thousands, you and giyuu both are in highschool currently and you are the popular kid while giyuu is the quiet and shy kid

You were planning on having a party so you invited a bunch of your friends and decided to invite giyuu as well. Giyuu was a bit shocked that someone as popular as you would invite him to a party but he gladly accepted

Now you both just have to get ready for the party and see how the night goes
