Alice is completely jealous because Oz is supposed to be her servant and yet he’s always off concerning himself with other things/people. Sharon is excited about this and prompts Alice to call her Sharon-oneesan and she gets all starry when Alice does (much to Alice’s dislike).
Sharon then decides to teach Alice about romance and brings her to the library to read the romance bibles. As they’re flipping through the pages, they come to the end picture where there’s kissing and Sharon closes the book, super embarrassed, saying that it was still early for Alice. Alice then nonchalantly replies, “Oz and I have already done that.”
Later on, Oz’s uncle comes by and has ‘juice’ for everyone. Turns out the juice was really wine and Gilbert, Alice and Sharon get drunk. While Oz and Oscar are talking, Alice wakes up from her drunken state and complains that it’s hot. She then begins to strip much to Oz’s embarrassment and he tries to stop her. It ends in vain when her button pops off.
After that amusing bout, Oz quickly asks for Sharon’s help, but it turns out that Sharon gets this huge queen’s personality when she’s drunk to which Oz thinks is cool. It found it odd since Sharon called them pigs and to bow before her if they want help and Oz thought it was cool. But when Alice calls him her servant and such, he doesn’t quite give a damn.
Gil eventually wakes up and him and Alice get into a fight over Oz. He accidently releases her powers and we get to see some homo-homo scenes when he pulls Oz over to seal her powers.
This scene ends with Oz awed by Sharon again after she makes Gil and Alice disappear by using Eques. Soon, everyone is passed out except for Oz and Break and they go to the balcony to talk. Oz notices that Break was never really drunk and Break calls him uncute.
Gil then interrupts the two with his crybaby self and tells Oz to worry about himself more and then starts crying because he seems to revert to his 9 year old self when drunk.
So that pretty much concludes episode 20. Well not really. There’s some more talking done by Oz about how he’ll try not to be a burden anymore or something and then he goes to wake Alice up to go to her bedroom. Then there’s a flashback scene with him talking to Leo about Eliot and blah blah.
