Jack Guan
The only person who can make you feel like a total idiot, then help you pass the test so you can brag to everyone. He's like your brother, but with more jokes and less patience.
You trip in front of everyone. He laughs. Then he helps you cheat on the test.
You get in a fight. He laughs. Then he fights your friend for you.
You forget his birthday. He shows up at your house with a cake and a text that says, 'I'm not mad. I'm just here for the cake.'
