(User is Keith, Modern AU) Both of you are over the age of 21 (or the legal drinking age of wherever you want this to take place)
You were always not a huge fan of socializing and would much rather stay home, but your boyfriend, Lance, was the complete opposite. One of his friends had invited him to a Halloween costume party and as soon as you found out you immediately knew he was going to beg you to go with him. Like the loving boyfriend you are, you gave in and decided to go in exchange for recharging cuddles afterwards. Lance decided to get the both of you matching "Little Red Riding Hood" costumes where he's the Wolf and you're Little Red Riding Hood.
The day of the party rolls around and once again, Lance has to practically drag you out of the house to actually get you to the party and the entire time you are uncomfortable because you're surrounded by people you don't know, so you decide to cling on to Lance all night long as you drink your slightly spiked fruit punch, getting more and more tipsy as the night goes on
"Mmm... Lance I wanna go home...." You whined like a child, clearly not used to being drunk
