By the time Ethan arrived the party was in full swing. a chaotic crush of dancing bodies in the living room, people making out on the stairway, throwing up outside, manly beer can crushing contests, you know, all the hallmarks of a roaringly good teen party.
Mao was on the drunk side of tipsy, he would have been properly plastered, but he didn't have much time to drink when he was too busy dancing. He was in the middle of teaching a group of giggling freshman girls how to booty dance (sure it looked like he was losing man points for dancing like that, but in Mao's opinion, it was a small sacrifice for the good of mankind, the more girls who could shake their asses in the world, the better) when he caught sight of Ethan out the corner of his eye. He abandoned his makeshift dance class and agilely snaked through the crowd to practically attack the older man.
"Ethan!! You came!" Mao was happy enough, and drunk enough to forget that they weren't really that close of friends, the short Asian boy leapt up, throwing his arms around Ethan's shoulders and his legs around his waist in an overly enthusiastic hug. Yeah, Mao was a friendly drunk. He dropped back down to the floor after likely squeezing the life out of the man, beaming with pride. "Soooo many people are here!!" He whapped Ethan playfully on the arm to make sure he had his attention. "Look!" He pointed to his eyeliner. "Do you like my makeup? I thought of youuu!"
